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: top - 06:23:14 up 4 days, 11:06, 1 user, load average: 2.26, 2.15, 2.18 Tasks: 126 total, 1 running, 125 sleeping, 0 stopped, 0 zombie Cpu(s): 50.2%us, 0.4%sy, 0.0%ni, 49.1%id, 0.2%wa, 0.0%hi, 0.1%si, 0.0%st Mem: 8047368k total, 8004516k used, 42852k free, 1507160k buffers Swap: 8388600k total, 57284k used, 8331316k free, 79700k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 17110 root 20 0 4417m 3.9g 1464 S 201.3 50.9 1326:34 qemu-kvm 9886 root 20 0 2519m 1.9g 1376 S 1.7 25.1 72:40.73 qemu-kvm 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.
