Opened BZ for small mem leak
by Daniel Helgenberger 28 Oct '14

28 Oct '14

Hello Sven and Dan, just FYI I opened a BZ [1] for the small mem leak of VDSM, 300KiB since Sven reported the same thing and it is there (and still is) since a long time now. With some help of us it might be pinpointed; the growth is quite linear. [2] Also, I think the issue might be neglectable in many / most production environments.

Re: [ovirt-users] CoreOS can not install on Ovirt
by Brian Harrington 28 Oct '14

Punit, Former Red Hatter and current "coreo" here. First which image are you trying to load? Your best bet will be to use the QEMU image. Also take a look at the console and see what the boot: line being supplied is. --Brian 'redbeard' Harrington > Hi, > > I try to install the CoreOS (https://coreos.com/) as guest VM under ovirt > 3.5 by ISO...but if i choose this CoreOS iso.... > > [image: Inline image 1] > > But if i choose Centos iso...it start the installation without any problem > ....i already checked the ISO of CoreOS is perfectly fine...i can install > it with physical machine...but stuck in the OVirt... > > Thanks, > Punit

MacPoolRanges not working as expected
by Xavier Naveira 28 Oct '14

28 Oct '14

Hi everyone, First of all I'd like to say that we have been using oVirt successfully for more than a year, creating an automated deploy system with help of foreman and puppet. That being said, we're currently facing the first serious problem and we'd appreciate some help. Everything was working fine until we exhausted the default MacPoolRanges. After looking for a solution to the error message we found this document: http://www.ovirt.org/Engine_config_examples#MacPoolRanges Following the instructions on it we executed the following commands: First we found out what our current pool was: # engine-config -g MacPoolRanges MacPoolRanges: 00:1a:4a:24:26:00-00:1a:4a:24:26:ff version: general So we proceeded to expand it: # engine-config -s "MacPoolRanges=00:1a:4a:24:26:00-00:1a:4a:24:27:ff" # service ovirt-engine restart After this we were able to create new machines but none of them seemed to have network. After some unsuccessful troubleshooting we restored the original pool and instead added a new one: # engine-config -s "MacPoolRanges=00:1a:4a:24:26:00-00:1a:4a:24:26:ff" # service ovirt-engine restart # engine-config -s "MacPoolRanges=00:1a:4a:24:26:00-00:1a:4a:24:26:ff,00:1a:4a:24:27:00-00:1a:4a:24:27:ff" # service ovirt-engine restart After doing this and test to create a new host everything seemed to work fine. The problem is that after the successful creation of some hosts the original problem where the new hosts didn't seem to have network, reappeared. Trying to narrow down the problem what we've find out so far is: This oVirt environment kickstarts hosts via PXE, when trying to PXE boot a new host, the DHCP process fails (timeout). Tracing the network packets, we are able to see that the virtual host sends the dhcp request, the dhcp server receives it and acknowledges it and it sends the dhcp offer back. The dhcp offer reaches the hypervisor to the vnetxx network interface BUT it doesn't go further and it doesn't reach the virtual host. This behavior is consistent through different hypervisors and vlans, including the ones that have been used/created before the problems appeared. The only pattern that we've been able to identify so far is through issuing the command "brctl showmacs <bridge_name>" This command list the mac addresses for the interfaces connected to the bridge. In the cases where everything works fine the output looks like this: port no mac addr is local? ageing timer 2 00:1a:4a:24:27:e0 no 0.01 2 fe:1a:4a:24:27:e0 yes 0.00 The virtual host MAC address begins with "00" and it has a corresponding address beginning with "fe" which is assigned to the "vnetxx" interface in the hypervisor. In the cases where the virtual host doesn't get the dhcp answers the output of "brctl showmacs <bridge_name>" is: port no mac addr is local? ageing timer 6 fe:1a:4a:24:27:a0 yes 0.00 This is, the actual virtual host's MAC address is missing from the bridge. We haven't been able to find a detailed explanation on how the network internals of oVirt should work but hopefully someone in this list can point us to the right resource. Thank you. Xavier.

oVirt 3.5 on RHEL 6.6 hyperv enabled breaks Windows VMs
by Charles Gruener 28 Oct '14

28 Oct '14

https://bugzilla.redhat.com/show_bug.cgi?id=1110305 This enabled the hv_relaxed flag on all my Windows VMs, causing them to no longer boot. The same thing would happen if I simply booted from the Windows install media. I would get a screen with a stop error: Your PC needs to restart. Please hold down the power button. Error Code: 0x0000001E Parameters: 0xFFFFFFFFC0000096 0xFFFFF802C4044EA4 0x00000000000000000 0x00000000000000000 I created a file called /etc/ovirt-engine/osinfo.conf.d/01-windows.properties that had one line: os.windows_xp.devices.hyperv.enabled.value = false I restarted ovirt-engine and now I can start my Windows VMs. Why does this occur? Is it because I upgraded from 3.4 to 3.5? Is there something else I'm doing wrong? I would like to not need this workaround. Thanks. Charles

Re: [ovirt-users] oVirt 3.5 & NAT

Well, in fact have got something to work now! Left ovirtmgmt and em1 alone but ran: $ ovs-vsctl add-br ovsbr0 $ ip link add name veth0 type veth peer name veth1 $ brctl addif ovirtmgmt veth0 $ ovs-vsctl add-port ovsbr veth1 $ ip add add XXX.XXX.XXX.XXX/29 dev veth1 $ ip link set veth0 up && ip link set veth1 up and now veth1 is responding as-well as veth0. ovs-vsctl show 08554d11-3ba7-4303-b9d5-6a09f23c9057 Bridge "ovsbr0" Port "veth1" Interface "veth1" Port "ovsbr0" Interface "ovsbr0" type: internal so what I think should do now is create a custom parameter on the Engine Manager that allows one to define an OVS bridge name and VLAN so when a virtual guest is created it can be assigned to the new bridge; with the use of a custom hook.

So at that point you have network running. If you then try to add that to the OVS stack your networking stop :( I tried to add it as a port using ovs-vsctl add-port ovsbr0 ovirtmgmt which is accepted but then networking stops. As soon as I remove again networking comes back to life.

You could just make a hook script that runs an after_network_setup hook that does the ovs-vsctl for you ;-) Here you can see the presentation I gave last February at devconf about extending with configurators and hooks. http://blog.antoni.me/devconf14/#/8/1 I linked directly to a before_network_setup hook sample, because it works just like the after_network_setup hook. Instead of logging to systemd, just add that if 'remove' is not in data and network == 'ovirtmgmt', it adds the network bridge to the vswitch with python's subprocess.call or subprocess.check_output. You can send it if you want me to take a look ;-) PS: It is possible to write the hooks in bash, c, perl, etc. But we only have the convenience read_json methods and such for python. If you wanted to, you could have a simple bash hook that just checked if there was an ovirtmgmt bridge and it would add it doing ovs-vsctl in the before_vdsm_start hooking point. That would have the drawback that changing the ovirtmgmt bridge with oVirt UI would leave it disconnected again. > > Thanks, Phil > > ----- Original Message ----- > From: "Antoni Segura Puimedon" <asegurap(a)redhat.com> > To: "Phil Daws" <uxbod(a)splatnix.net> > Cc: "Dan Kenigsberg" <danken(a)redhat.com>, users(a)ovirt.org > Sent: Monday, 27 October, 2014 9:56:38 AM > Subject: Re: [ovirt-users] oVirt 3.5 & NAT > > > > ----- Original Message ----- > > From: "Phil Daws" <uxbod(a)splatnix.net> > > To: "Antoni Segura Puimedon" <asegurap(a)redhat.com> > > Cc: "Dan Kenigsberg" <danken(a)redhat.com>, users(a)ovirt.org > > Sent: Monday, October 27, 2014 10:37:18 AM > > Subject: Re: [ovirt-users] oVirt 3.5 & NAT > > > > That is what I tried but oVirt appears to overwrite the bridge information > > on > > boot :( Thanks, Phil > > But before rebooting, does it work as you intended?

Nevertheless a host reinstall from webadmin gui seemed to fix the problem and after that it was able to start vdsm ad host part. I was also able to upgrade DC/Cluster from 3.4 to 3.5 version. Now that I'm on 3.5 next days I'll try to pass from F19 to F20... we'll see Gianluca

oVirt 3.5 & NAT
by Phil Daws 27 Oct '14

27 Oct '14

Hello All! Am really enjoying experimenting with oVirt but have come across a question; how does one enable NAT for a VM ? Would like my guests to be able to update their software by bridging the host public IP. I could not see anything in the WUI to allow this ? Thanks, Phil
