Hello, I've just migrated a bunch of guests from one node to another due to upgrading host kernel from 2.6.37 to 2.6.37.1. After that, some of guests started consuming 100% of CPU time and their os seems to be stuck.
Looks like all the stuck guest were running 2.6.32 with kvm paravirt enabled. others running same as well as different kernels seem to be ok, including windows guests. I guess I can keep stuck guest in this state for few hours, so if somebody would be willing to have a look at this, I'll be happy to try to help. running kvm_stat for few seconds reports: kvm_exit 237284 19119 kvm_entry 237183 19119 kvm_emulate_insn 123548 10088 kvm_mmio 92947 7622 kvm_exit(IO_INSTRUCTION) 90744 7395 kvm_pio 90726 7395 kvm_exit(EXCEPTION_NMI) 69993 5416 kvm_page_fault 69254 5347 kvm_apic 51528 4157 host is x86_64, guests were x86_64 too..
