Subject: qemu-kvm process is running at 100% CPU, but no response from guest
Date: Thu, 9 Jul 2009 07:18:54 +0200 [thread overview]
Message-ID: <20090709051854.GP15329@salstar.sk> (raw)
Hello,
today I have second incident, that my qemu-kvm process is running at 100%
or 200% CPU (watched using top program), but there is no response from guest
long time (some hours). First time lots of these messages appeared in dmesg:
vcpu not ready for apic_round_robin
vcpu not ready for apic_round_robin
vcpu not ready for apic_round_robin
Second time nothing, only process was run at 200% CPU:

Serial console without response too in boch cases, no ping to guest.
My current configuration is an fully updated Fedora 11 host and updated
Fedora 10 guest. KVM is from package qemu-kvm-0.10.5-3.fc11.x86_64.
I have no cpufreq or cpuspeed installed on my system, so there is no cpu
frequency scaling.
Other 2 similar host installations have no similar problems.
Thank you for help.
