[Users] iso domain in maintenance and VMs cannot start
It is obvious that when an VM has a iso attached and the iso domain is in maintenance the VM cannot start. When I try to start such an VM the engine only reports that it cannot be started (failed to run VM on hv1, hv2, hv3) with no further error. I looked at engine.log and vdsm.log and there is also no specific error, that the ISO isn't accessible. PS: - ovirt 3.3 - detaching the iso allows the vm to start of course. -- Ernest Beinrohr, AXON PRO DevOps, Ing http://www.beinrohr.sk/ing.php, RHCE http://www.beinrohr.sk/rhce.php, RHCVA http://www.beinrohr.sk/rhce.php, LPIC http://www.beinrohr.sk/lpic.php, VCA http://www.beinrohr.sk/vca.php, +421-2--6241-0360 callto://+421-2--6241-0360, +421-903--482-603 callto://+421-903--482-603 icq:28153343, skype:oernii-work callto://oernii-work, jabber:oer...@jabber.org For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled.

Other than checking highly available, is there another step that needs to be made for a VM to be restarted on a working host should the host it is running on fail? Migration does not work when the host crashes. If you have fencing enabled, the engine can restart the dead host and start the vms on another host. This works for us.

Hi list,
I need to move 600+ vms:from one data domain to another, however from
what i can see in the GUI i can only move one vm disk at the time
which would be very time consuming.
I there any way i can bulk move those vm disks?
By the way, I can't stop the vms they have to be online during the
migration..
This is my python program:
# ... API init
vms= api.vms.list(query = 'vmname')
for vm in vms:
print vm.name
for disk in vm.disks.list( ):
print " disk: " + disk.name + " " + disk.get_alias()
sd = api.storagedomains.get('NEWSTORAGE')
try:
disk.move(params.Action(storage_domain=sd))
disk_id = disk.get_id()
while True:
print("Waiting for movement to complete ...")
time.sleep(10)
disk = vm.disks.get(id=disk_id)
if disk.get_status().get_state() == "ok":
break
except:
print "Cannot move."
api.disconnect()

[ovirt-users] Unable to start VM after 4.2 upgrade
Hi, I updated my engine and 1 host to 4.2 from 4.1 and now I cannot
start a VM and get this error:
"UnsupportedType: Unsupported {} for ioTune".
My other 6 4.1 hosts are able to start VM normally with the new 4.2 engine.
My VM has this inside: total_bytes_sec="0" total_iops_sec="0" write_bytes_sec="0"
write_iops_sec="100"/>

[ovirt-users] Hosts force fencing after engine upgrade 4.3->4.4
Hi, I was in the process of upgrading 4.3 to 4.4. First I upgraded the engine
and the hosts are still 4.3. The engine has started fencing my hosts as there
has been 1 (one) connection problem to VDSM on the host. I Basically, the
engine at some random time connects to vdsm, this crashes (didnt on e4.3) and
after a few seconds the engine issues a fencing and all my VMs are taken down
This happend with multiple hosts at random times. Can this be attributed to the
unmatched hosts? Or should I consider an engine restore to 4.3?

[ovirt-users] Is it possible to auto-start VMs on single LocalStorage host without the engine?
I currently use KVM/virsh for my DNS. I would like it to ovirt, but I need DNS started for the engine to work. So I need to start the DNS vm before the engine. Is that possible with ovirt? I was thinking I could use the same mechanism as hosted engine, as that would autostart. In my current KVM setup I needed only to symlink /etc/libvirtd/qemu/dns.xml to /etc/libvirtd/qemu/autostart/ to get it to run. ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/JPREYFWDOYKCPIBL75QGSHCNNS333KMJ/
