Re: Virtual machines volume lock manager
true, true... Forgot these cases while I was running KVM. Check if that VM is using a compute offering which is marked as "HA enabled" - and if YES< then Wei is 100% right (you can confirm this from logs - checking for info on starting that VM on specific hypervisor etc) THough, IF doing live migration, I assume it should play fair/nice with HA and HA should not kick in. Wei can you confirm if these 2 play together nice ^^^ ?

Re: Virtual machines volume lock manager
I would advise trying to reproduce. start migration, then either: - configure timeout so that it''s way too low, so that migration fails due to timeouts. - restart mgmt server in the middle of migrations This should cause migration to fail - and you can observe if you have reproduced the problem. keep in mind, that there might be some garbage left, due to not-properly handling the failed migration But from QEMU point of view - if migration fails, by all means the new VM should be destroyed...

Re: Number of hosts in a cluster
No limit for KVM (false docs), but don't abuse, due to too many KVM hosts i.e. accessing same cluster-wide primary storage etc. But otherwise, no technical limits.

Number of hosts in a cluster
Hello In the documentation, I see that there is a configuration requirement of not adding more than 16 hosts in a cluster: "For KVM, do not put more than 16 hosts in a cluster." In our setup, we have more than 18 nodes in a cluster without any issues so far. So I wanted to know what is the actual limit of hosts in a cluster. I didn't see any such value in global setting as well. If there is no such limitation then we need to update the documentation. -- Thanks and regards Rakesh venkatesh
Re: Virtual machines volume lock manager
Hi Andrija Sorry for the late reply. Im using 4.7 version of ACS. Qemu version 1:2.5+dfsg-5ubuntu10.40 Im not sure if ACS job failed or libvirt job as I didnt see into logs. Yes the vm will be in paused state during migration but after the failed migration, the same vm was in "running" state on two different hypervisors. We wrote a script to find out how duplicated vm's are running and found out that more than 5 vm's had this issue.
