** Description changed:
- I Use Ubuntu 32 bit 10.04 with standerd kvm.
- I have E7600 @ 3.06GHz processor with VMX
+ 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/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin
QEMU_AUDIO_DRV=none /usr/bin/kvm -M pc-0.12 -enable-kvm -m 256 -smp 1 -name

.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 scsi virtual disk and writeback simultaneously.
- writeback+ide, writethrough+scsi works OK.
+ 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 radom place during file copy. It seems, when
+ Virtual machine get down at random time during file copy. It seems, when
qcow2 file size need to be expanded.
