Hello.
I'm struggeling a little bit with the setvcpus command. I'm trying now
to get this running for a linux VM. Here is what i have:
<vcpu placement='auto' current='2'>4</vcpu>
Now the VM is starting with 2 CPUs. When i try to increase the number of
CPUs i get:
setvcpus dev --guest 4
error: invalid argument: requested vcpu count is greater than the count
of enabled vcpus in the domain: 4 > 2
This sets the current number of cpus and that cannot be changed live
(unless you have cpu hot(un)plug).
Strange thing is when i set in the xml file:
<vcpu placement='auto' current='4'>4</vcpu>
the VM starts with 4CPUs and setting the CPUs works.
Because the max is 4 and you're setting the "current" number.
I can do:
setvcpus dev --guest 2
and:
setvcpus dev --guest 4
Is this a bug? Should i try to upgrade to 1.2.10? There seem to be a lot
of changes in it regarding setvcpus.
thanks and cheers
