[Bug 574665] Re: kvm + virtio disk corrupts large volumes (>1TB).

[zyro]

i can confirm this issue. virtio plus guest volumes (qcow2/raw seems
irrelevant, tried both with errors) >1T causes image corruption. the
used disk space in the guests did not matter in my case. io errors
showed sometimes at 10gb, sometimes later when already ~750gb were
copied onto the virtual disk.

additionally, lucid 10.04 server partitioner freezes while trying to
create ext4 fs on virtual disk > 1T with virtio. only workaround here
was to run setup with ide driver, switching to virtio afterwards. but
again, that caused disk corruption after some time (varied between
minutes and days).

atm using one 250G virtio raw image and one 2T ide raw image stable
without any flaws.
