<br />> <br />No, not without restarting the guest from scratch. Whilst it's
<br />> possible <br />to REDUCE the processor count, you can't increase it
after
<br />> it's been <br />started [actually, the technicality of it is that
there's a
<br />> MAX_CPU <br />count in the domain config parameters, which is hidden
from
<br />> the config <br />files at present, but that is the number of VCPU's
<br />> "reserved" when the <br />domain is set up, and with a normal config
file,
<br />> you get MAX_VCPUS=VCPUS <br />at the domain creation].

<br />> So if I want to get a guest with 2 VCPUs, I must install a new one? no
<br />> other ways?
<br />
<br />Just change the config file, shut down the guest and then start it again.
<br />
<br />As long as the guest has an SMP-capable kernel, it should pick up the
extra
<br />VCPUs straight away.
Firstly sry forgot to CC to list just now
I did so, change the VCPU=2, but when I reboot the guest, it will halt with
blackscreen(see the attached 1.png) after start. xm list shows the VCPU is
already 2 now.
puzzled why it hangs :(
Checked my guest kernel, SMP.
Thanks
