This is a multi-part message in MIME format. Hi, I have a server dual xeon quad core with gentoo and qemu: app-emulation/qemu-kvm-0.12.3-r1 USE="aio gnutls ncurses sasl vde -alsa -bluetooth -curl -esd -fdt -hardened -kvm-trace -pulseaudio -qemu-ifup -sdl -static" There is a lot of vm running with ubuntu and fedora that running without problems. I installed one vm with latest gentoo amd64, stage3 and portage. When I try to do an emerge -e world the process freeze after a while, any time in differente package and there aren't any errors in the logs. This is a screenshot of the freezed vm: http://yfrog.com/0iscre1j top - 10:00:50 up 10:53, 2 users, load average: 0.00, 0.00, 0.00 Tasks: 130 total, 1 running, 124 sleeping, 0 stopped, 5 zombie Cpu(s): 0.1%us, 0.0%sy, 0.0%ni, 99.9%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 8194776k total, 886508k used, 7308268k free, 225080k buffers Swap: 2048248k total, 0k used, 2048248k free, 476956k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1 root 20 0 3760 656 552 S 0 0.0 0:00.86 init 2 root 20 0 0 0 0 S 0 0.0 0:00.00 kthreadd 3 root RT 0 0 0 0 S 0 0.0 0:01.78 migration/0 4 root 20 0 0 0 0 S 0 0.0 0:00.00 ksoftirqd/0 5 root RT 0 0 0 0 S 0 0.0 0:02.01 migration/1 6 root 20 0 0 0 0 S 0 0.0 0:00.01 ksoftirqd/1 7 root RT 0 0 0 0 S 0 0.0 0:02.05 migration/2 8 root 20 0 0 0 0 S 0 0.0 0:00.01 ksoftirqd/2 9 root RT 0 0 0 0 S 0 0.0 0:02.15 migration/3 10 root 20 0 0 0 0 S 0 0.0 0:00.01 ksoftirqd/3 11 root RT 0 0 0 0 S 0 0.0 0:01.69 migration/4 12 root 20 0 0 0 0 S 0 0.0 0:00.00 ksoftirqd/4 13 root RT 0 0 0 0 S 0 0.0 0:01.49 migration/5 14 root 20 0 0 0 0 S 0 0.0 0:00.00 ksoftirqd/5 15 root 20 0 0 0 0 S 0 0.0 0:00.11 events/0 16 root 20 0 0 0 0 S 0 0.0 0:00.21 events/1 ps -elf: 1 S root 776 2 0 80 0 - 0 scsi_e May18 ?

Kernel .config: http://pastebin.org/252943 With 2.6.32-r7 I notice the emerge will freeze after a lot of compiled packages, while with the 2.6.33 series after 30-40 compiled packages, emerge freeze. If I run vm without -smp there aren't any freeze of emerge. In the same server there are other VMs with ubuntu and -smp 6 and works without any problems. There is a limit max cpus for -smp ? for the total of the VMs running in the server? Any suggestions? It's possible to enable a log for what service?
