Dustin, rc2 in the PPA (1:84+dfsg-0ubuntu12.1~rc2ppa3) appears to have already fixed the segfault. No segfaults in 3 days and I've applied some high disk I/O to the machine. I can't test rc4 right away b/c rc2 is on a production machine. Once I can declare another maintenance window and reboot the machine, I'll try rc4.

[Bug 359447] Re: kvm segfaults
I'm running jaunty with everything up-to-date. I was experiencing segfaults similar to those described in this ticket when disk I/O was high. For example, when dd'ing a raw image file to an LVM volume, when the image was about 60G, caused several kvm processes to crash. I was able to reproduce these crashes in an interesting way: I gave a FreeBSD VM an AoE volume, with the following command line: /usr/bin/kvm -S -M pc -m 256 -smp 1 -name freebsd-test -uuid fa4f4230-ff42-012b-cef0-00163ec95f4c -monitor pty -boot c -drive file=/dev/mapper/vol1-freebsd--test,if=ide,index=0,boot=on -drive file=/dev/etherd/e0.1,if=ide,index=1 -net none -serial pty -parallel none -usb Slightly prior to booting this VM, I would turn off the AoE volume where it was exported from. When FreeBSD would try to mount it, the kvm process would crash within about 30 seconds. After installing the following ppa: 1:84+dfsg-0ubuntu12.1~rc2ppa3 I have not been able to reproduce the problem. Instead of the kvm process crashing, FreeBSD just reports a crap load of DMA errors: [r...@beta ~]# fsck /dev/ad1s1a ** /dev/ad1s1a ** Last Mounted on /backup ** Phase 1 - Check Blocks and Sizes ** Phase 2 - Check Pathnames ** Phase 3 - Check Connectivity ** Phase 4 - Check Reference Counts ** Phase 5 - Check Cyl groups 5939 files, 145406 used, 108409 free (2713 frags, 13212 blocks, 1.1% fragmentation) ad1: FAILURE - WRITE_DMA status=41 error=4 LBA=191 CANNOT WRITE BLK: 128 CONTINUE?

I hadn't looked at the guest when it crashed. It was just last message on serial console. I can't trigger it.Seems it's occurs only once a boot or under heavy io load. I can't experiment with a server because it's in production environment. I will make backups soon. If problem in io-subsystem it will crash again and I will try to reproduce it in another(testing) virtual container. -- kvm segfaults https://bugs.launchpad.net/bugs/359447 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 359447] Re: kvm segfaults
It seems the bug is somewhere in the block layer. The segfault is caused by the IDE DMA callback being called, but the embedded IDEState is NULL. Lots of stuff has changed in the block layer since kvm-84 came out, so this might prove tricky to narrow down. -- kvm segfaults https://bugs.launchpad.net/bugs/359447 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
