Hello.
Does someone know in what state setvcpu command is?
I get:
virsh # setvcpus gentookvm 4 error: internal error: cannot change vcpu count of this domain
and
error : qemuDomainHotplugVcpus:4087 : internal error: cannot change vcpu count of this domain
Does this work for someone?
It works for xen:// URIs. Upstream qemu vcpu hotplug is still a work in progress; I don't know if qemu 1.6 will support it, or if you'll have to wait for qemu 1.7. Meanwhile, you can try using 'setvcpus gentookvm --guest 4' to use the guest agent (assuming you have qemu-ga running in the guest, and the proper plumbing of the guest agent channel in your domain XML) to use the guest to take vcpus on- or offline.
Tried that with no luck so far. virsh # setvcpus gentookvm --guest 2 error: internal error: unable to execute QEMU agent command 'guest-get-vcpus': The command guest-get-vcpus has not been found It's qemu-1.4.2 and libvirt-1.1.1. In general it seems to work. virsh # shutdown 3 --mode agent Domain 3 is being shutdown Any hints? And once again, thanks for your support Eric. cheers t.
