Hosted engine datastore crashed on adding a new datastore
by Klas Mattsson 25 Apr '14

25 Apr '14

Hello all, For some reason, when I try to add a second datastore (separate IP and empty share with 36:36 user rights), the share which has got the hosted-engine on it crashes. This of course crashes the hosted engine. When the share is up again, it's not sufficient to create a directory /rhev/data-center/mnt/ with identical name as before and mounting the share there. The hosted-engine still refuses to boot up. The load (pure I/O) on the NFS server goes up to about 11 as well. Any ideas on where I should check?

Storage domain - defining fields
by Gabi C 25 Apr '14

25 Apr '14

Hello! My setup 1 engine Fedora 19 ovirt 3.4 managing 3 nodes Fedora 19 + ovirt 3.4 updated; those nodes acts also as gluster server for 2 storage domains, each domain 3 bricks replicated ( so 3 bricks each). I have one questions regarding the fields one have to complete when defining a new storage domain and its importance. First, field "*Use Host*" - you have to complete with one of the nodes. Of course you can use any of the host in cluster, *but which is its significance/importance*? * If you reboot that node, you suppose to have any issue with the storage?* The same question with field "*Path*" - gluster case - "*Path to gluster volume to mount*" formatted as "HOST:VOLUME" , where host can be the same as above mentioned field- "*Use Host*" or any af the gluster cluster member; *which is its significance/importance?* *Again If you reboot that node, you suppose to have any issue with the storage?* My experience with rebooting these nodes*, *after moving VM's and putting it in Maintenance was good*,* until yesterday, when after such reboot I've got some corrupted VM images, and subsequently I had to restore them. Error message follows : Exit message: cannot read header '/rhev/data-center/mnt/glusterSD/10.125.1.194:gluster__data3/5fe658b1-43ff-4bfd-97d6-28217cf415df/images/321ad473-3741-4825-8ac0-6c416aa8f490/1a21454d-9931-4ed8-ba38-7126528664a1': Input/output error." Did I miss some step(s), beside moving VM's and puting node in maintenace, before reboot one host node, servig also as gluster node? Any hint, link would be appreciated! Thanks!

Hi All, I'm having an issue with oVirt 3.4 and Foreman 1.5 RC1 at the moment, it does not start/finish a new provisioned VM/Host., it creates it well on oVirt.

Spurious error message when the RHEV capacity is maxed out?
by Satya Vempati 24 Apr '14

24 Apr '14

--_000_CF7D45AF5E0Esvempatitintricom_ Content-Type: text/plain; charset="Windows-1252" Content-Transfer-Encoding: quoted-printable We have about 900 vms in a RHEV-M 3.3 installation (3.3.2-0.50.el6ev) with = three hosts. Each VM has 1 socket, 1 core for CPU and 256 MB memory and 2 x 1TB disks + = one 5 GB boot disk. Each host has 2 cpu sockets with 4 cpu cores per socket. When we power on about 250 of these vms, we cannot power on any more vms. Attempting to do so gets the error (in the RHEV-M) console. Bad volume specification {'index': 0, 'iface': 'virtio', 'reqsize': '0', 'f= ormat': 'raw', 'bootOrder': '1', 'volumeID': '14aa7302-7f6d-4b80-922d-3fc09= 0695447', 'apparentsize': '5368709120', 'imageID': '97b1985e-e507-4927-91e9= -7393c7777de5', 'specParams': {}, 'readonly': 'false', 'domainID': '0c7abcc= c-1b97-4b39-ab96-e977a19fac3a', 'optional': 'false', 'deviceId': '97b1985e-= e507-4927-91e9-7393c7777de5', 'truesize': '0', 'poolID': '5849b030-626e-47c= b-ad90-3ce782d831b3', 'device': 'disk', 'shared': 'false', 'propagateErrors= ': 'off', 'type': 'disk'}. This looks like a spurious error, as we can power on the same VM after rebo= oting the hosts. And also, the hosts do not really look maxed out (CPU usage is around 25%, = memory around 50%), but no more vm=92s can be powered on.

Anyone using gluster storage domain with WAN geo-rep?
by Steve Dainard 23 Apr '14

23 Apr '14

I'm currently using a two node combined virt/storage setup with Ovirt 3.3.4 and Gluster 3.4.2 (replica 2, glusterfs storage domain). I'll call this pair PROD. I'm then geo-replicating to another gluster replica pair on the local net, btrfs underlying storage, and volume snapshots so I can recover my storage domain from different points in time if necessary. Its also local so restore time is much better than off-site. I'll call this pair BACKUP. I'm planning on setting up geo-replication from BACKUP to an EC2 gluster target. I'll call this host EC2HOST. PROD ---geo-rep-lan---> BACKUP ---geo-rep-wan---> EC2HOST I'd like to avoid saturating my WAN link during office hours. I have some ideas (or combination of): 1. limit bandwidth during certain hours to the offsite hosts. But realistically the bandwidth I would allocate is so low I don't see the purpose of this. Also with 8 guests running, I'm noticing quite a bit of data transfer to the local backup nodes (avg 6-8MB/s), and I'm thinking there is a lot of thrashing going on which isn't useful to backup offsite anyways. 2. stop WAN geo-replication during office hours, and restart for overnight/weekend hours. 3. Not use geo-rep between BACKUP ---> EC2HOST, use rsync on one of the btrfs volume snapshots so we avoid the thrashing. In this case I could limit WAN speed to 1MB/s which should be fine for most differences throughout the day. So my question is, how do you off-site your storage domains, what constraints have you identified and how have you dealt with them? And of course how would you deal with the scenario I've oulined above? Thanks, *Steve*

difference between thin/depentend and clone/dependent vm virtual machine
by Tamer Lima 23 Apr '14

23 Apr '14

Hello, I created VMs by two ways : 1) on tab virtual machines > new vm > template (centos_65_64bits) 1.1 configuration : I do not select stateless checkbox 1.2 this process takes a 1h30 to create each machine. 2) on tab pools > new vm > template (centos_65_64bits) 2.1 default configuration : stateless 2.2 Here I created 3 virtual machines at once 2.3 this process takes only one minute On the tab virtual machines I can see all virtual machines. Pooled machines have different icon image and description is different too: machines generated from tab VM are described as clone/dependent - clone is a phisical copy? machines generated from tab POOL are described as thin/independent - thin is a just a reference to template vm ? what is phisical? any configuration file? In practice, what is the difference between these machines ? http://www.ovirt.org/Features/PrestartedVm "Today there are 2 types of Vm pools: 1. Manual - the Vm is supposed to be manually returned to the pool. In practice, this is not really entirely supported. 2. Automatic - once the user shuts down the Vm - it returns to the pool (stateless)." all vm created from pool are stateless ? thanks

[ACTION REQUESTED] please review new oVirt look-and-feel patch
by Greg Sheremeta 23 Apr '14

23 Apr '14

Hi, A while back, I sent out an email for the new oVirt look-and-feel feature [1]. The new look and feel patch is ready for both code and UI review. At this point we're not looking for design review, although you are welcome to suggest design improvements. I'm mostly looking for help regression testing the entire UI. Especially if you're an oVirt *UI* developer, please download the patch and try it [2]. The patch introduces some new CSS globally, and I had to adjust many screens and dialogs. It's quite possible that there are dialogs that I don't know about, so if you maintain any especially-hidden dialogs, please try the patch and verify your dialogs look good. And you can also just try out the patch to see the amazing new look and feel! Thanks for your feedback.

hosted engine health check issues
by René Koch 23 Apr '14

23 Apr '14

Hi, I have some issues with hosted engine status. oVirt hosts think that hosted engine is down because it seems that hosts can't write to hosted-engine.lockspace due to glusterfs issues (or at least I think so). Here's the output of vm-status: # hosted-engine --vm-status --== Host 1 status ==-- Status up-to-date : False Hostname : 10.0.200.102 Host ID : 1 Engine status : unknown stale-data Score : 2400 Local maintenance : False Host timestamp : 1397035677 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=1397035677 (Wed Apr 9 11:27:57 2014) host-id=1 score=2400 maintenance=False state=EngineUp --== Host 2 status ==-- Status up-to-date : True Hostname : 10.0.200.101 Host ID : 2 Engine status : {'reason': 'vm not running on this host', 'health': 'bad', 'vm': 'down', 'detail': 'unknown'} Score : 0 Local maintenance : False Host timestamp : 1397464031 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=1397464031 (Mon Apr 14 10:27:11 2014) host-id=2 score=0 maintenance=False state=EngineUnexpectedlyDown timeout=Mon Apr 14 10:35:05 2014 oVirt engine is sending me 2 emails every 10 minutes with the following subjects: - ovirt-hosted-engine state transition EngineDown-EngineStart - ovirt-hosted-engine state transition EngineStart-EngineUp In oVirt webadmin I can see the following message: VM HostedEngine is down. Exit message: internal error Failed to acquire lock: error -243. These messages are really annoying as oVirt isn't doing anything with hosted engine - I have an uptime of 9 days in my engine vm. So my questions are now: Is it intended to send out these messages and detect that ovirt engine is down (which is false anyway), but not to restart the vm? How can I disable notifications? I'm planning to write a Nagios plugin which parses the output of hosted-engine --vm-status and only Nagios should notify me, not hosted-engine script. Is is possible or planned to make the whole ha feature optional? I really really really hate cluster software as it causes more troubles then standalone machines and in my case the hosted-engine ha feature really causes troubles (and I didn't had a hardware or network outage yet only issues with hosted-engine ha agent). I don't need any ha feature for hosted engine. I just want to run engine virtualized on oVirt and if engine vm fails (e.g. because of issues with a host) I'll restart it on another node.

Hi list, if you do not already monitor some security lists: You are strongly encouraged to update your qemu-kvm packages, especially on CentOS :) See below for details -------- Original-Nachricht -------- Betreff: [RHSA-2014:0421-01] Moderate: qemu-kvm-rhev security update Datum: Tue, 22 Apr 2014 17:52:38 +0000 Von: <bugzilla(a)redhat.com> An: <rhsa-announce(a)redhat.com>, <rhev-watch-list(a)redhat.com> ===================================================================== Red Hat Security Advisory Synopsis: Moderate: qemu-kvm-rhev security update Advisory ID: RHSA-2014:0421-01 Product: Red Hat Enterprise Virtualization Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0421.html Issue date: 2014-04-22 CVE Names: CVE-2014-0142 CVE-2014-0143 CVE-2014-0144 CVE-2014-0145 CVE-2014-0146 CVE-2014-0147 CVE-2014-0148 CVE-2014-0150 ===================================================================== 1. Summary: Updated qemu-kvm-rhev packages that fix several security issues are now available for Red Hat Enterprise Virtualization. The Red Hat Security Response Team has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: RHEV Agents (vdsm) - x86_64 3. Description: KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the user-space component for running virtual machines using KVM in environments managed by Red Hat Enterprise Virtualization Manager. Multiple integer overflow, input validation, logic error, and buffer overflow flaws were discovered in various QEMU block drivers. An attacker able to modify a disk image file loaded by a guest could use these flaws to crash the guest, or corrupt QEMU process memory on the host, potentially resulting in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2014-0143, CVE-2014-0144, CVE-2014-0145, CVE-2014-0147) A buffer overflow flaw was found in the way the virtio_net_handle_mac() function of QEMU processed guest requests to update the table of MAC addresses. A privileged guest user could use this flaw to corrupt QEMU process memory on the host, potentially resulting in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2014-0150) A divide-by-zero flaw was found in the seek_to_sector() function of the parallels block driver in QEMU. An attacker able to modify a disk image file loaded by a guest could use this flaw to crash the guest. (CVE-2014-0142) A NULL pointer dereference flaw was found in the QCOW2 block driver in QEMU. An attacker able to modify a disk image file loaded by a guest could use this flaw to crash the guest. (CVE-2014-0146) It was found that the block driver for Hyper-V VHDX images did not correctly calculate BAT (Block Allocation Table) entries due to a missing bounds check.

Re: [ovirt-users] Ovirt + GLUSTER

Nothing too complicated. SL 6x and 5 8 vm hosts running on a hitachi blade symphony. 25 Server guests 15+ desktop windows guests 3x 12TB storage servers (All 1TB based raid 10 SSDs) 10Gbs PTP between 2 of the servers, with one geolocation server offsite. Most of the server images/luns are exported through 4Gbps FC cards from the servers using LIO except the desktop machines with are attached directly to the gluster storage pool since normal users can create them. Various servers use use the gluster system directly for storing a large number of documents and providing public access to the tune of about 300 to 400 thousand requests per day. We aggregate, provide public access, efiling, e-payments and case management software to most of the illinois circuit court system. Gluster has worked like a champ.

converting windows guests with v2v, where to put the iso?
by Jeremiah Jahn 22 Apr '14

22 Apr '14

I'm getting the following error. RedHat seems to thin the answer is to use their virtio-win rpm. As far as I can tell, this is not available anywhere, So I've just got to go and get the iso that it installs from kvm.org. Ok, done. now that I have said iso, where the heck do I put it, since it doesn't seem to align with the structure that v2v is looking for. virt-v2v: Installation failed because the following files referenced in the configuration file are required, but missing: /usr/share/virtio-win/drivers/i386/WinXP

Query for adding non kvm hosts to ovirt engine
by Peter Harris 22 Apr '14

22 Apr '14

I have a small test environment, where I am trying to work out the detail of configuring ovirt + gluster as our main customer support environment. All boxes running Scientific Linux 6.5 and ovirt 3.4 and glusterfs 3.5: mgr1 : ovirt-engine installed and vdsm-gluster vmhost1 : main vm server, added to mgr1 as host vmhost2 : second vm server, add to mgr1 as host strg1 : first gluster storage server strg2 : second gluster storage server mgr1 is an old box, hardware does not support virtualization vmhost1 and vmhost2 have full vt capability strg1 and strg2 hardware does not support virtualization In the past, if I have created a gluster only ovirt-engine install, I have been able to add strg1 and strg2 as hosts. Is there any way I can use mgr1 to manage both vm hosts and storage hosts, and add strg1 and strg2 to mgr1 as hosts. At the moment, I get the following error: 2014-04-22 10:27:37 DEBUG otopi.ovirt_host_deploy.hardware hardware._isVirtualizationEnabled:186 virtualization support GenuineIntel (cpu: False, bios: True) 2014-04-22 10:27:37 DEBUG otopi.ovirt_host_deploy.hardware hardware.detect:202 Hardware supports virtualization 2014-04-22 10:27:37 DEBUG otopi.context context._executeMethod:152 method exception Traceback (most recent call last): File "/tmp/ovirt-2p0fjrQMTb/pythonlib/otopi/context.py", line 142, in _executeMethod method['method']() File "/tmp/ovirt-2p0fjrQMTb/otopi-plugins/ovirt-host-deploy/vdsm/hardware.py", line 68, in _validate_virtualization _('Hardware does not support virtualization') RuntimeError: Hardware does not support virtualization Many thanks
