I was used to take live snapshot with qemu-kvm-rhev-0.12.1.2-2.355.el6.5.x86_64 which was recompiled from the redhat srpms, because live snapshot was not supported by the official qemu-kvm in el6.4. * Does now 6.5 include the correct qemu-kvm version for live snapshot? * If not why does redhat provide a separate qemu package for RHEV while fedora has got the correct package? * Does ovirt team provide support for el6 live snapshot "out of the box" or do they recommend to get the correct qemu-kvm version from the rhev repository? Assuming that redhat doesn't provide the same qemu-kvm in rhev than in el6, what about including qemu-kvm-rhev in the ovirt el6 repository as dreyou did ?

[Users] How do I add a node?

by Rob Abshear

This is a multi-part message in MIME format. --------------070509040507000705010302 Content-Type: text/plain; charset=US-ASCII; format=flowed I am thoroughly confused at this point. I have three servers. One for a controller and two for nodes. These servers were used as an oVirt environment just last week. But, now, when I try to do a fresh installation with the exact same configuration as before, I can't add nodes. Here is the process I used previously: 1. Install Fedora (minimum install) on each machine 2. Install tar on each node machine 3. Install the engine on the controller machine. 4. Add nodes using IP and password in the web admin interface and let the controller build the node. 5. Profit. Now that procedure does not work. When I try it that way, the node installs and then fails with an error that it can't configure the management network on the node. I have a second working oVirt environment, but I can't even add the nodes into that one. So, I decide to try installing using the oVirt Quick Start document located at http://www.ovirt.org/Quick_Start_Guide. The problem is that, there is no "oVirt Engine" tab in the administration app. It's my understanding from the document that this is how you tell the node which controller it should be allowing. I can't add the nodes that I built with the oVirt Node Installation CD. The documentation on this is so sparse that I can't figure out what's going on. It was so easy to set up before, but I'm having nothing but trouble, now. I have been at this for days, when the first time took me about an hour. What am I missing? Could someone either update the Quick Start guide, or reply with some up-to-date instructions on how to install this environment? FYI, I am doing this with completely fresh installs of Fedora 19. No software is being reused or reconfigured. It's completely stock. Controller=192.168.165.70 Node01=192.168.165.71 Node02=192.168.165.72 All are connected via the same switch. I can ping all the three machines from each other. If I try to ssh from the controller into either of the nodes, I get "Read from socket failed: Connection reset by peer". If I attempt to ssh into either of the nodes from another machine on the network, I get the same message. If I try to add either node using the web interface, It fails with: Error while executing action: Cannot add Host. Connecting to host via SSH has failed, verify that the host is reachable (IP address, routable address etc.) You may refer to the engine.log file for further details.

[Users] virt-v2v fail - GuestfsHandle.pm error + Redhat.pm error

by Nicolas Ecarnot

Hi, After having successfully migrated Debian, XP, 2003, 2008 VMs, I'm stuck with a migration I was expecting to be easy : RHAS3. Here is the error log I get : > # virt-v2v -i libvirt -ic qemu+ssh://xxxx@xxxx/system -o rhev -os xxxx:/data/vmexport -of qcow2 -oa sparse -n ovirtmgmt serv-rhas3-vm1 > serv-rhas3-vm1_copy.raw: 100% [=====================================================================================================]D 0h10m14s > virt-v2v: Pas de capability dans la configuration correspondant à os='linux' name='virtio' distro='rhel' major='3' minor='0' > virt-v2v: Pas de capability dans la configuration correspondant à os='linux' name='cirrus' distro='rhel' major='3' minor='0' > virt-v2v: WARNING: Le pilote d'affichage a été modifié en cirrus, mais il est impossible d'installer le pilote cirrus.

But here, the last two lines are lethal. It seems oVirt tries to guess which OS is imported, and tries to do specific actions, and do them bad. Either there's a way o prevent oVirt from guessing, either there's a way to correct the actions oVirt is failing to do... Googling was not that helpful about this issue. Regards. -- Nicolas Ecarnot

[Users] Ovirt Gluster problems

by Juan Pablo Lorier

This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --K1RorUOWmjDsov5Mv5auigJcOlmISEK1x Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Hi, I had some issues with a gluster cluster and after some time trying to get the storage domain up or delete it (I opened a BZ about a deadlock in the process of removing the domain) I gave up and destroyed the DC. The thing is that I want to add the hosts that where part of the DC and now I get that I can't as they have the volume. I try to stop the volume but I can't as no host is running in the deleted cluster and for some reason, ovirt needs that. I can't delete the hosts either as they have the volume... so I'm back in another chicken and egg problem. Any hints?? PD: I can't nuke the hole ovirt plataform as I have another DC in production.... otherwise I would :-) Regards, --K1RorUOWmjDsov5Mv5auigJcOlmISEK1x Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJS5+vaAAoJEC5KDDg2+NMMHR4H/1kf5+MMK9VMbNn0cNLXOsDL pLcFHMAqq5+C5XvA0CrKgsEpTNvkjH49X3hB/ulhwDtXDJBLcoHVC+mAoqMmbkeQ 1bJaUCNQtst9BYOtJ4eq5ZXCGpB7rvEe5wZGuBeJqZUFnJ1FekVc3F1RXbfBmVeE ELQlJ0rp4cufZod8TwNh1O+wSx0nVHC9TJPKPSPA/qKMqrG2IIiR/3wGlFpeu3QJ eBcvixk7wf8YyxGvOwBDYVoc4+tYCHmqHiGAj6E6lDAVDySgvRTg/wH5OkoYGpn1 tSRiLWlSzd1A+XpKveOabPdBfOKqSoSUTfgq+NiwTD/9cKJuElb2g5F6UycjPAw= =oHX+ -----END PGP SIGNATURE----- --K1RorUOWmjDsov5Mv5auigJcOlmISEK1x--

[Users] oVirt 3.4 test day - results

by Alexander Wels

Hi, I tested the following items during the test day and here are my results: 1. "reboot VM" functionality The related feature page is: http://www.ovirt.org/Features/Guest_Reboot The feature page mentions a policy selection checkbox which I was unable to find in the web admin UI at all. I checked the patches that implement the feature and did not see the check box implementation. The patches did show me that all I need to use the feature was to install the guest agent on the guest. So for my test I installed a fedora guest, and I installed the guest agent on the guest. After about a minute after starting the guest, the reboot button was enabled and pressing it started the reboot sequence on the guest. I had a console open on the guest and it informed me that the admin had started the reboot process and the guest would be rebooted in a minute. I did not find a way to change the time it took for the reboot to happen. I did the same test with the REST api, with the same result. The reboot was scheduled for a minute after I issued the command. I did not find a way to change the time with the REST api either. I am guessing that is a future feature. 2. Fix Control-Alt-Delete functionality in console options I had trouble getting spice to work in my test setup, but no issues with VNC. So I tested VNC. I checked the VM console options to make sure that 'Map ctrl-alt-del shortcut to ctrl+alt+end' was checked. Then I connected to a running VM with VNC. I pressed ctrl-+alt+end expected it to issue a ctrl-alt-del to the guest. Nothing happened. I pressed ctrl-alt-del and it properly issued ctrl-alt-del to the guest. I made sure there was no issue with my client by using the menu to issue a ctrl-alt-del to the guest which also resulted in the proper action on the guest. I opened a bug for this: /https://bugzilla.redhat.com/show_bug.cgi?id=1057763/[1] I did this test on my Fedora machine, and the description mentions that certain OSes capture the ctrl-alt-del before sending it to the guest, Fedora is not one of those OSes, so maybe my test was not valid? 3. Show name of the template in General tab for a VM if the VM is deployed from template via clone allocation. This is a very straight forward test. I created a template from a VM. I named the template. Then created a VM from that template using clone allocation. I verified that the name of the template is now properly shown in the VM general sub tab. Works as expected. Overall I had issues getting engine installed due to the shmmax issue reported in other threads, and then I had a really hard time adding new hosts from a blank fedora minimum install. I was successful one out of three attempts, which I feel was probably an yum repository issue as I was getting conflicting python-cpopen issues causing VDSM to not start. Thanks, Alexander -------- [1] https://bugzilla.redhat.com/show_bug.cgi?id=1057763

[Users] spice html5 - windows inverted

by Neil Schulz

Good Morning Everyone, I installed the Spice guest tools on my windows machine and now everything is inverted. I am unable to use the machine anymore. The biggest issue was the mouse not syncing up. That issue was solved after installing the tools, however the inverted screen kind of makes that fix pointless. Is there a fix to this? Along with that, I haven't noticed it on a Windows 2008 R2 server yet, however, I cannot use Ctl+Alt+Delete in Spice HTML5 to test it. Thank you, Neil

[Users] Xeon 5060 support "Dempsey"

by Peter Galgano

Thanks in advance for any help you can provide We are testing Ovirt 3.2.2 on a 2007 vintage dual Xeon 5060 (Dempsey) Supermicro Superserver. http://en.wikipedia.org/wiki/Xeon#5000-series_.22Dempsey.22. This hardware runs Centos 6.5 and KVM / virt manager just fine, and we have be running many virtual machines on this hardware with reasonable performance for many years We are getting the message: "Non-Operational state as host does not meet the cluster's minimum CPU level" each time we create a host. After researching this list, we are coming to the conclusion that this older processor is not being recognized by ovirt. Output of virsh -r capabilities and vdsClient -s 0 getVdsCaps are posted below. We havent found anyone with exactly this use case in our research. The closest thread is this: http://lists.ovirt.org/pipermail/users/2012-May/007536.html This poster was able to add some lines to the db to recognize his processor. Here is the advice he received in that post. > ok, indeed an old host. > the below config is what we used before going to the 'model' approach, so you can try this out (though highly recommended for newer cpu since they improved virt support in each generation) > > set the ServerCPUList config to this string for the relevant cluster compatibility level. > > I'm not sure upgrade won't override this for you though, so pay attention on upgrades to such a low level tweak (it's config, but not all configs are really expected to be changed by user) > > '2:Intel Xeon w/o XD/NX:vmx,sse2:qemu64,-nx,+sse2; 3:Intel Xeon:vmx,sse2,nx:qemu64,+sse2; 4:Intel Conroe Family:vmx,sse2,nx,cx16,ssse3:qemu64,+sse2,+cx16,+ssse3; 5:Intel Penryn Family:vmx,sse2,nx,cx16,ssse3,sse4_1:qemu64,+sse2,+cx16,+ssse3,+sse4.1; 6:Intel Nehalem Family:vmx,sse2,nx,cx16,ssse3,sse4_1,sse4_2,popcnt:qemu64,+sse2,+cx16,+ssse3,+sse4.1,+sse4.2,+popcnt; 2:AMD Opteron G1 w/o NX:svm,sse2:qemu64,-nx,+sse2; 3:AMD Opteron G1:svm,sse2,nx:qemu64,+sse2; 4:AMD Opteron G2:svm,sse2,nx,cx16:qemu64,+sse2,+cx16; 5:AMD Opteron G3:svm,sse2,nx,cx16,sse4a,misalignsse,popcnt,abm:qemu64,+sse2,+cx16,+sse4a,+misalignsse,+popcnt,+abm;' We think we understand what is happening: our processors capabilities will be matched by processor type line 2 or 3, and then the host won't be rendered "non-operational". My Questions: 1. is this the correct change to ServerCPUList config in the db, 2. Is this the proper way to get support for older processors? 3. Is this documented anywhere? Can someone please help with a step by step for less experienced users? 4. Wouldn't it be reasonable to expect Ovirt to support processors that KVM supports by default? What is the minimum perceived processor expected to be? why is is conroe, when perfectly functional processors a few months older cause errors? The server hardware we are using is fine for our purposes, we don't intend to upgrade for this purpose.at this time.

Re: [Users] How to setup FreeBSD 8.3 Guest on oVirt 3.3

by Dresel Christopher

Sure already tried that - IDE, no Ethernet at all, everything related to VirtIO disabled - no success. Quoted from the forum: "It has nothing to do with the virtio driver. It is a more deeply rooted problem inside KVM in its emulation of CPU's over Intel chipsets in combination with *BSD amd64." As I already virtualized pfSense with an older Version of Intel Chipset (Sandy Bridge) with KVM and Hardware Virtualization I really think it's related to the newer Haswell chipset. The same configuration with an i386 ISO build works. Best Regards, Christopher -----Original Message----- From: René Koch [mailto:rkoch@linuxland.at] Sent: Donnerstag, 30.

Btw, does FreeBSD boot if you use an IDE disk and e1000 NIC (did go quickly through the proxmox forum thread and issues seem to be virtio related)? This will decrease performance for sure, but maybe it's sufficient. My Solaris vms are for compiling and Puppet module tests, so IDE and e1000 emulated devices are fine for me.

[Users] Python SDK list vms slow, excessive cpu usage

by Sander Grendelman

Fetching the list of vms through the API with the python SDK takes several seconds[1] with 100% cpu usage in the python script. When I look at the engine log there is only one (fast) fetch from the API. The rest of the time is spent in the SDK processing a relatively small bit of XML data (only 26 VMs in my environment). This seems an excessive amount of CPU for processing ~6KB of XML. I've included some sample code [2] and output [3]. Attached is the cProfile output for this call and a visualization. [1] ~6,5 seconds on an oVirt VM with 1 vcpu on older hardware, ~3,5 seconds on a fast physical machine with an i5 cpu. [2] Sample code, add your own url/credentials/certificate: #!/usr/bin/python """Get ovirt VM names""" import time from ovirtsdk.api import API from ovirtsdk.xml import params def print_elapsed(logString): elapsed = time.time() - startTime print "%fs %s" % (elapsed, logString) startTime = time.time() print_elapsed("before connect") api = API( url="https://my.engine.url/api", username="user@domain", password="password", ca_file="./ca.crt", ) print_elapsed("after connect") print_elapsed("before fetch list") vmList = api.vms.list() print_elapsed("after fetch list") print_elapsed("before use list") count = 0 for vm in vmList: vmName = vm.get_name() count += 1 print "\t number of VMs %d" % count [3] Example of output: [grendelmans@bungee src]$ /usr/bin/time ./vm_list_test.py 0.000003s before connect 0.338248s after connect 0.338299s before fetch list 6.795967s after fetch list 6.796041s before use list number of VMs 26 6.796181s after use list 7.28user 0.05system 0:07.64elapsed 96%CPU (0avgtext+0avgdata 84624maxresident)k 0inputs+0outputs (0major+5605minor)pagefaults 0swaps [grendelmans@bungee src]$

[Users] Networking. Hosted Setup. All in One Host. Hetzner

by Peter Styk

Greetings, I'm writing here as to share some of my findings about hosting with Hetzner. All in one setups on single remote host can be tricky. Provider mounted an extra /29 subnet to the main host but none is routed by default and host has to become router itself. At the same time single mistake in bridging configuration and lost access results in need for re-bootstrap. It's still tempting to try and with many trials I eventually got to see guests talking to the net. Scenario 1: Working. Package bridge-utils, oVirt engine, setup bridge, VDSM, add host to engine, add routing to host routing table. Networking by trial and error. Still something is not right. Occasionally on ping out I'm getting "Redirect Host (New nexthop" messages. http://styk.tv/wp-content/uploads/2014/01/oVirtHosted1_almost_working.png Scenario 2: Dreaming. Private network with private router/dhcp/nat. Private 10.0.0.0/24 network. No problems with routing as gateway 10.0.0.1 would be on the same subnet. Thought of using pfSense but can't seem to bring up an instance with two network cards on two different networks. I thought this would be easy. Go to Networks, click create new network, type private, save ok. then go to new instance. point at iso, attach two network cards. save ok. Launch "Host did not satisfy internal filter Network" No idea what that is. Maybe I don't understand how this works. I even tried removing ovirtmgmt network and leaving private network by itself. Tried with all 3 network card types (rtl8139/e1000/VirtIO) http://styk.tv/wp-content/uploads/2014/01/oVirtHosted2_preferred.png Either way if you have a minute or two please take a look at both attached diagrams. Deliberately making it difficult by forcing all elements on single box in hosted environment. Maybe there is a way to have this all installed with Neutron or vSwitch on the same box or is that pushing it? Regards, Peter
