Bug Description
I Use Ubuntu 32 bit 10.04 with standard KVM.
I have Intel E7600 @ 3.06GHz processor with VMX
In this system I Run:
LC_ALL=C PATH=/usr/
.iso image contain custom distro of 2.4-linux kernel based system. During install process (when .tar.gz actively unpacked), kvm dead with segmentation fault.
And ONLY when I choose scsi virtual disk and writeback simultaneously.
But, writeback+ide, writethrough+scsi works OK.
I use qcow2. It seems, that qcow does not have such problems.
Virtual machine get down at random time during file copy. It seems, when qcow2 file size need to be expanded.
IMPACT: kvm used with scsi virtual disk and writeback dies with segfault.
FIX: is the inclusion of a patch cherry-picked from upstream which dequeues
requests before invoking callbacks. It is at
http://
TO REPRODUCE: See the command above.
REGRESSION POTENTIAL: this is cherry-picked from upstream, and has been
tested by the bug reporter with no ill effects.
