Summary: Ubuntu 10.04 installer fails due to I/O errors with virtio
Initial Comment:
I tried installing Ubuntu 10.04 and Fedora 12 in a KVM virtual machine using
virtio, on a 8G raw file-backed disk. Both installers failed half-way due to
I/O errors. So I tried reproducing it and managed to repeat it 6 times. The bug
doesn't occur with IDE emulation. The bug happens fairly quickly with -smp 4 --
usually within 5 minutes -- but is much rarer with -smp 1.
Ubuntu installer has kernel 2.6.32-11-generic
Fedora 12 has kernel 2.6.31.5-127.fc12.x86_64
Host has kernel 2.6.32.6 (Arch Linux) and QEMU 0.12.2
When testing with -smp 1, it also produced a kernel oops from
block/blk-core.c:245. This line warns when the function is called with
interrupts enabled:
void blk_start_queue(struct request_queue *q)
{
WARN_ON(!irqs_disabled());
queue_flag_clear(QUEUE_FLAG_STOPPED, q);
__blk_run_queue(q);
}

Summary: Ubuntu 10.04 installer fails due to I/O errors with virtio
Initial Comment:
I tried installing Ubuntu 10.04 and Fedora 12 in a KVM virtual machine using
virtio, on a 8G raw file-backed disk. Both installers failed half-way due to
I/O errors. So I tried reproducing it and managed to repeat it 6 times. The bug
doesn't occur with IDE emulation. The bug happens fairly quickly with -smp 4 --
usually within 5 minutes -- but is much rarer with -smp 1.
Ubuntu installer has kernel 2.6.32-11-generic
Fedora 12 has kernel 2.6.31.5-127.fc12.x86_64
Host has kernel 2.6.32.6 (Arch Linux) and QEMU 0.12.2
When testing with -smp 1, it also produced a kernel oops from
block/blk-core.c:245. This line warns when the function is called with
interrupts enabled:
void blk_start_queue(struct request_queue *q)
{
WARN_ON(!irqs_disabled());
queue_flag_clear(QUEUE_FLAG_STOPPED, q);
__blk_run_queue(q);
}
