hi,

in proxmox 2.2 there was a command cpu_set
in pve 2.3 i didn't find them anymore.

however, the command was not working but will there be the possibility to hotplug cpu(cores) w/o rebooting in the near future?

thanks,
argonius

cpu_set has never work correctly.
a new cpu-add command has been added to qemu 1.5
http://wiki.qemu.org/Features/CPUHotplug

So yes, it should come soon in proxmox, when qemu will be updated. (currently proxmox use qemu 1.4).

Note that unplug is not yet supported, cpu-add is a temporary workaround, because qemu dev need to implement this is a cleaner way, with device_add/device_del commands. (see qemu wiki)

Hi,

thanks for your answer. Do you have an eta when qemu 1.5 will be deployed into proxmox? is there a way, to get this by myself?

thanks
