Message-ID: <CE5DB0F4.8F0D%markt@netqa.com> (raw)
Hello,
I have been using 'qemu-nbd' and 'qemu-img' for some time to provide
loop filesystems in my environment.
Recently I have been experimenting with hibernating (suspend to disk)
the physical host on which I have qemu running.
I am using the kernel functionality directly with the commands:
echo platform >/sys/power/disk
echo disk >/sys/power/state
The following appears in dmesg when I attempt to hibernate:
====================================================
[ 38.881397] nbd (pid 1473: qemu-nbd) got signal 0
[ 38.881401] block nbd0: shutting down socket
[ 38.881404] block nbd0: Receive control failed (result -4)
[ 38.881417] block nbd0: queue cleared
[ 87.463133] block nbd0: Attempted send on closed socket
[ 87.463137] end_request: I/O error, dev nbd0, sector 66824
====================================================
My environment:
Debian: 6.0.5
Kernel: 3.3.1
Qemu userspace: 1.2.0
Thank you for any thoughts on this one.
Regards,
Mark Trumpold
