Number of VMs can be created on a KVM host.
Hi, All,
When I tried to create more than 2 VMs on my 2 KVM hosts, it failed
by "Unable
to create a deployment for VM[User|i-2-17-VM], Please check the affinity
groups provided, there may not be sufficient capacity to follow them". But
each KVM host has 24 cores, 48GB RAM and 8TB of disk, the instance I tried
to create is a anapshot of a VM which is 100GB size. Seems each KVM host
could only create one VM here. So not clear what's the problem? Any
parameters to tune? Thanks.
Cheers,
Dan

as far as I know, that is the only option (host anti-afinity)...let me know
if you find the issue...

Thanks Andrija, it works without affinity groups, not sure what wrong with
it, but I could not see the details about the group, only type of "host
anti-affinity".
Cheers,
Dan

Hi Dan, could you please try to create VMs without using afinity groups,
and provide MS log output...
