Re: [Xen-users] reboot needed to increase vcpus??

[Shane Johnson <sdj@xxxxxxxxxxxxxxxxxxxxxx>]

Dan,

From what I have seen, it depends on if you are using PV or HVM DomU's.  PV you can use the xm vcpu-set {domain} {#vcpus} and you should be good to go.  HVM you can use the same command but the Guest will have to be rebooted in order to see the update.

If you are using a updated xen the command is xl I believe (I am on Debian squeeze for my host so the commands above are what I use)

Shane

P.S. Sorry if this gets double posted.

In order to address a performance issue (or try to) I'd like to allocate 4 vcpus to a domU. I think I need to increase that setting in dom0's /etc/xen domU file. Is that correct? And do I need to reboot either or both of dom0 and/or domU subsequently? and is there a corresponding setting in domU?

Thanks. As you can see I'm new at this.
