Manual VM Migration fails
by Anton Louw 26 Oct '20

26 Oct '20

Hello Everybody, I am having a strange issue. When I try and manually migrate a VM from one host to another, I get an error stating: "Migration failed (VM: VM1, Source: node6.example.com, Destination: node3.example.com)" I have tried with a few different machines, and it pops up with the same error. I have attached the VDSM logs of both source and destination nodes. The time frame is 16:01 I see the below in that time frame, but not quite sure what I need to change: 2020-10-23 16:01:14,419+0200 ERROR (migsrc/42186f82) [virt.vm] (vmId='42186f82-b84c-7e65-e736-e6331acd04ed') Failed to migrate (migration:450) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 431, in _regular_run time.time(), migrationParams, machineParams File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 505, in _startUnderlyingMigration self._perform_with_conv_schedule(duri, muri) File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 591, in _perform_with_conv_schedule self._perform_migration(duri, muri) File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 525, in _perform_migration self._migration_flags) File "/usr/lib/python2.7/site-packages/vdsm/virt/virdomain.py", line 100, in f ret = attr(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/common/libvirtconnection.py", line 131, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/common/function.py", line 94, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 1781, in migrateToURI3 if ret == -1: raise libvirtError ('virDomainMigrateToURI3() failed', dom=self) libvirtError: operation failed: guest CPU doesn't match specification: missing features: spec-ctrl,ssbd Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

oVirt test clustered DOA after upgrade to latest 4.4.2 (AFAIK). Network issue?
by Gilboa Davara 26 Oct '20

26 Oct '20

Hello all, I just upgraded one of my test oVirt setups to latest. Post reboot, the machine lost network and hosted engine didn't start. When I connected to the machine, I noticed all the /etc/sysconfig/network-scripts/ifcfg-* files disappeared. No idea why / how. (Possibly I did something wrong and forgot about it.) Long story story short, I copied the two missing files (ifcfg-onb0 ethernet device configuration and the ifcfg-ovirtmgmt bridge configuration) from another ovirt host, changed the ovirtmgmt IP address and UUID to match the UUID reported in logs as missing and restarted NetworkManager and restarted all the oVirt related services (vdsmd, supervdsmd, ovirt-*, etc). Sadly enough, even with both onb0 and ovirtmgmt up, vdsm still complains about the missing network (ovirtmgmt) and refuses to start the hosted engine. Reboot doesn't seem to change anything. In the main log I see the following errors: Oct 22 16:33:31 office-wx-otest vdsm[2634]: WARN Attempting to remove a non existing network: ovirtmgmt/1da8c5b7-999c-4ada-8287-1f35de6ce21d Oct 22 16:33:31 office-wx-otest vdsm[2634]: WARN Attempting to remove a non existing net user: ovirtmgmt/1da8c5b7-999c-4ada-8287-1f35de6ce21d Oct 22 16:33:31 office-wx-otest vdsm[2634]: WARN Attempting to remove a non existing network: ovirtmgmt/1da8c5b7-999c-4ada-8287-1f35de6ce21d Oct 22 16:33:31 office-wx-otest vdsm[2634]: WARN Attempting to remove a non existing net user: ovirtmgmt/1da8c5b7-999c-4ada-8287-1f35de6ce21d As it is one of my oVirt test setup, I can simply redeploy the host and continue from there, but I rather use this experience to learn how to fix oVirt such issues in the future.

sr-iov network config assistance IOMMU group error
by Edward Berger 26 Oct '20

26 Oct '20

I'm' trying to bring up a test ovirt 4.4 cluster with sr-iov virtual infiniband interfaces on Mellanox ConnectX-6 cards in some older Opteron servers while we await delivery of new Epyc servers. I have the hypervisors configured for sr-iov and showing the interfaces, but when I try to bring up a VM with the host device selected it fails to boot. "Failed Launching ..." shows up on the engine UI. [image: sriov-hostdev.JPG] The /var/log/libvirt/qemu log for the VM seems to think something is wrong with the IOMMU group. If I scroll over to the right it says N/A under the IOMMU column. Is there some step I need to 'create IOMMU groups' or any other suggestions?

ovirt Storage Domain Cluster Filesystem?
by lsc.oraes＠gmail.com 23 Oct '20

23 Oct '20

Hi all I come from Oracle VM x86 world and we are planning from moving Oracle VM to oVirt. I am having hard time understanding Storage Domains in oVirt. All our storage are SAN and I wonder how can we manage SAN LUN in oVirt to create a storage domain such that the VM guests can run in any host in the oVirt Cluster? For example in Oracle VM the Storage Repository (it is the Storage Domain in OVM words) are based on SAN LUNs and on top of that a cluster filesystem is created so all hosts in the cluster have concurrent access to the storage repository and the VM guest can be started in any of the hosts in the cluster. How do we accomplish the same in oVirt with SAN Storage? Which Cluster Filesystem is supported in Storage Domain? Or perhaps in oVirt the mechanism is totally different? Thank you

Re: Gluster volume not responding

Hi Simon, Usually it is the network, but you need real-world data. I would open screen sessions and run ping continiously . Something like this: while true; do echo -n "$(date) "; timeout -s 9 1 ping -c 1 ovirt2 | grep icmp_seq; sleep 1; done | tee -a /tmp/icmp_log Are all systems in the same network ? What about dns resolution - do you have entries in /etc/hosts ? Best Regards, Strahil Nikolov В неделя, 11 октомври 2020 г., 11:54:47 Гринуич+3, Simon Scott <simon(a)justconnect.ie> написа: Thanks Strahil. I have found between 1 & 4 Gluster peer rpc-clnt-ping timer expired messages in the rhev-data-center-mnt-glusterSD-hostname-strg:_pltfm_data01.log on the storage network IP. Of the 6 Hosts only 1 does not have these timeouts. Fencing has been disabled but can you identify which logs are key to identifying the cause please. It's a bonded (bond1) 10GB ovirt-mgmt logical network and Prod VM VLAN interface AND a bonded (bond2) 10GB Gluster storage network. Dropped packets are seen incrementing in the vdsm.log but neither ethtool -S or kernel logs are showing dropped packets. I am wondering if they are being dropped due to the ring buffers being small.

Based on this one I make the following conclusions: 1. Issue is reoccuring 2. You most probably have a network issue Have you checked the following: - are there any ping timeouts between fuse clients and gluster nodes - Have you tried to disable fencing and check the logs after the issue reoccurs - Are you sharing Blackup and Prod networks ? Is it possible some backup/other production load in your environment to "black-out" your oVirt ? - Have you check the gluster cluster's logs for anything meaningful ?

New host: no network interfaces visible
by Richard Chan 23 Oct '20

23 Oct '20

What could cause no Network Interfaces visible in installing a new host? I have added a new host to oVirt 4.3.10, the initial SSH installs all the packages (all with failed=0 in host-deploy/*log). The installation is shown as failed without any meaningful message. However the Network Interfaces page is blank, what could cause this? Host in CentOS 7.8 tried with/without biosdevname. -- Richard Chan
