Category: intel Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Alex Davis (alex14641) Assigned to: Nobody/Anonymous (nobody) Summary: Second KVM process hangs eating 80-100% CPU on host Initial Comment: Second KVM process hangs eating 80-100% CPU on host during startup Host software: Linux 2.6.24.4 KVM 65 (I am using the kernel modules from this release). X11 7.2 from Xorg SDL 1.2.13 GCC 4.1.1 Glibc 2.4 Host hardware: Asus P5B Deluxe (P965 chipset based) motherboard 4 GB RAM Intel E6700 CPU bitness: 64-bit Guest software: Slackware 12.0 installed from CD-ROM. bitness 32-bit Command used to first KVM instance: /usr/local/bin/qemu-system-x86_64 -hda /spare/vdisk1.img -cdrom /dev/cdrom -boot c -m 384 -net nic,macaddr=DE:AD:BE:EF:11:29 -net tap,ifname=tap0,script=no & Command used to start second KVM instance: /usr/local/bin/qemu-system-x86_64 -hda /spare/vdisk2.img -cdrom /dev/cdrom -boot c -m 384 -net nic,macaddr=DE:AD:BE:EF:11:30 -net tap,ifname=tap1,script=no & tap0 and tap1 are bridged on the host. The guest OS was installed on /spare/vdisk1.img, which was initially created by /usr/local/bin/qemu-img create -f qcow /spare/vdisk.img 10G After the guest installation completed, vdisk1 was copied to vdisk2. The second instance always stops after printing Checking if the processor honours the WP bit even in supervisor mode... Ok. Running top on the host at this point shows the kvm process using 80-100% CPU. The second instance stays hung until I press the return key in the first instance; sometimes clicking in another X window will wake it up as well. This is a test machine so I can test patches (almost) at will. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=1944969&group_id=180599 ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
