Dear All, I am using version 1.0 of qemu-kvm along with 3.2.x host+guest kernels on an X86_64 server. I was unable to trigger a hotplug of a vCPU from the qemu's monitor prompt (tripped over an assertion in qemu). Tried to look through the recent archives and noticed a couple of proposed fixes. One for this assertion and another to trigger the actual SCI notification. Not sure if they were official fixes or not... I tried it out with these 2 fixes. I noticed that the cpuX showed up in the /sys/devices/system/cpu/ subdir. I was however not able to activate the newly hotplug'd vCPU via "echo 1 > cpuX/online". Looks like the vCPU isn't waking up in the guest. If there is any [proposed|official] fix available that I could try out for this issue..pl point me to the same. Thanks in anticipation!
