|
||
|
|
. `sudo virsh setvcpus <guest> <num_of_cpus> --config` - ie:
|
||
|
|
+
|
||
|
|

====
|

Note that using [.title-ref]#virsh reboot# is insufficient. You have to

||
|
|
actually stop the domain and start it with `virsh destroy <guest>` and
|
||
|
|
`virsh start <guest>` for the change to take effect.

you set, if appropriate.
