Hi all,

To increase a VM performance I launched the command xm vcpu-set domU 2 to add an other processor to my VM.

Where can I check if it works knowing that the command xm list dont show a changed cpu nember ?

[root@localhost ~]# xm list
Name                                      ID Mem(MiB) VCPUs   State Time(s)
Domain-0                             0     4035     4        r----- 29851.8
domU                                 3     2047     1       r----- 96114.6

[root@localhost ~]# xm vcpu-set 3 2

[root@localhost ~]# xm list
Name                                      ID    Mem(MiB) VCPUs State   Time(s)
Domain-0                                0     4035          4   r----- 29852.2
domU                                    3     2047          1 r----- 96137.4

An other question, is it healthy that I set more than 2 processors (4 for example) ?

Thanks in advance.
