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);
}

Follow-up: I have reproduced this bug with 0.12.2 and 0.12.1.
I tried 0.11.1, but this version does not seem to have this bug.
Also, here's another user's report of the same problem:

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);
}

A 'me too':
A 64-bit Intel (x86_64) based Fedora 12 host environment using the Fedora
12 "Virt-Preview" repository
(http://jforbes.fedorapeople.org/virt-preview/f12/x86_64/) for qemu
userspace. rpm in use at time of these oops()es was:
qemu-*-0.12.2-1.fc12.x86_64.
The IO problem occurred on the swap device (/dev/vda2), but it has also
been observed on the /dev/vda3 (root) device (ext3) and on the /dev/vda1
(boot) device (ext4). All of the devices with issues are hosted in a raw
image file on the host. The host reports no IO errors or disk related
problems.

Message:
Follow-up: I have reproduced this bug with 0.12.2 and 0.12.1.
I tried 0.11.1, but this version does not seem to have this bug.
Also, here's another user's report of the same problem:

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);
}

0.12.2-4 update of the qemu-system-x86_64 binaries didn't include any fix,
obviously). Hit both my swap (/dev/vda2) and root (/dev/vda3) file systems.

A 'me too':
A 64-bit Intel (x86_64) based Fedora 12 host environment using the Fedora
12 "Virt-Preview" repository
(http://jforbes.fedorapeople.org/virt-preview/f12/x86_64/) for qemu
userspace. rpm in use at time of these oops()es was:
qemu-*-0.12.2-1.fc12.x86_64.
The IO problem occurred on the swap device (/dev/vda2), but it has also
been observed on the /dev/vda3 (root) device (ext3) and on the /dev/vda1
(boot) device (ext4). All of the devices with issues are hosted in a raw
image file on the host. The host reports no IO errors or disk related
problems.

Follow-up: I have reproduced this bug with 0.12.2 and 0.12.1.
I tried 0.11.1, but this version does not seem to have this bug.
Also, here's another user's report of the same problem:

Can you check if the patch below fixes it?

From: Christoph Hellwig <hch@lst.de>
Subject: [PATCH v2] block: avoid creating too large iovecs in multiwrite_merge
If we go over the maximum number of iovecs support by syscall we get
back EINVAL from the kernel which translate to I/O errors for the guest.
Add a MAX_IOV defintion for platforms that don't have it. For now we use
the same 1024 define that's used on Linux and various other platforms,
but until the windows block backend implements some kind of vectored I/O
it doesn't matter.

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);
}

obviously). Hit both my swap (/dev/vda2) and root (/dev/vda3) file systems.

Follow-up: I have reproduced this bug with 0.12.2 and 0.12.1.
I tried 0.11.1, but this version does not seem to have this bug.
Also, here's another user's report of the same problem:

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);
}

obviously). Hit both my swap (/dev/vda2) and root (/dev/vda3) file systems.

A 'me too':
A 64-bit Intel (x86_64) based Fedora 12 host environment using the Fedora
12 "Virt-Preview" repository

qemu-*-0.12.2-1.fc12.x86_64.
The IO problem occurred on the swap device (/dev/vda2), but it has also
been observed on the /dev/vda3 (root) device (ext3) and on the /dev/vda1
(boot) device (ext4). All of the devices with issues are hosted in a raw
image file on the host. The host reports no IO errors or disk related
problems.

Message:
Follow-up: I have reproduced this bug with 0.12.2 and 0.12.1.
I tried 0.11.1, but this version does not seem to have this bug.
Also, here's another user's report of the same problem:

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);
}

Happened again, now less than 24 hours after rebooting the guest (the
0.12.2-4 update of the qemu-system-x86_64 binaries didn't include any fix,
obviously). Hit both my swap (/dev/vda2) and root (/dev/vda3) file systems.

A 'me too':
A 64-bit Intel (x86_64) based Fedora 12 host environment using the Fedora
12 "Virt-Preview" repository
(http://jforbes.fedorapeople.org/virt-preview/f12/x86_64/) for qemu
userspace. rpm in use at time of these oops()es was:
qemu-*-0.12.2-1.fc12.x86_64.
The IO problem occurred on the swap device (/dev/vda2), but it has also
been observed on the /dev/vda3 (root) device (ext3) and on the /dev/vda1
(boot) device (ext4). All of the devices with issues are hosted in a raw
image file on the host. The host reports no IO errors or disk related
problems.
The guest is started with:
