[Qemu-devel] [Bug 1185395] [NEW] qemu-1.5.0 savevm error -95 while writing vm with ceph-rbd as storage-backend

[Oliver Francke]

Public bug reported:

With a running VM I encounter this strange behaviour, former qemu-versions don't show up such an error.
Perhaps this comes from the rbd-backend in qemu-1.5.0 in combination with ceph-0.56.6?

( -95 might be a general "Operation not supported" error? )

Up to 1.4.2 everything is OK with savevm, though.

Any help welcome,

Oliver.

[Oliver Francke]

Sorry for not providing enough informations, here we go:

typical longish start for qemu is:

/usr/local/bin/qemu-system-x86_64 -usbdevice tablet -enable-kvm
-daemonize -pidfile /var/run/qemu-server/760.pid -monitor unix:/var/run
/qemu-server/760.mon,server,nowait -vnc unix:/var/run/qemu-
server/760.vnc,password -qmp unix:/var/run/qemu-
server/760.qmp,server,nowait -nodefaults -serial none -parallel none
-device rtl8139,mac=00:F1:70:00:2F:80,netdev=vlan0d0 -netdev
type=tap,id=vlan0d0,ifname=tap760i0d0,script=/etc/fcms/add_if.sh,downscript=/etc/fcms/downscript.sh
-name 1155823384-4 -m 512 -vga cirrus -k de -smp sockets=1,cores=1
-device virtio-blk-pci,drive=virtio0 -drive
format=raw,file=rbd:1155823384/vm-760-disk-1.rbd:rbd_cache=false,cache=writeback,if=none,id=virtio0,media=disk,index=0
-drive
format=raw,file=rbd:1155823384/vm-760-swap-1.rbd:rbd_cache=false,cache=writeback,if=virtio,media=disk,index=1
-drive if=ide,media=cdrom,id=ide1-cd0,readonly=on -drive
if=ide,media=cdrom,id=ide1-cd1,readonly=on -boot order=dc

after fired up I go to the monitor socket and try a:

QEMU 1.5.0 monitor - type 'help' for more information
(qemu) savevm test123
Error -95 while writing VM
(qemu) 

If I only let the error -95 happen and ignore, everything seems to be OK, though. Might be easy to fix, but not for me...
qemu up to 1.4.2 is not affected.

Please let me know, if you need more informations.

Oliver.

Triaging old bug tickets ... can you still reproduce this problem with
the latest version of QEMU (currently v2.9.0)?

Re: [Qemu-devel] [Bug 1185395] qemu-1.5.0 savevm error -95 while writing vm with ceph-rbd as storage-backend

[Oliver Francke]

Hi Thomas,

thnx for coming back on this. Currently on vacation, but just gave it a
shot on fresh compiled qemu-2.9.0:

—

savevm
Error while writing VM state: Operation not supported

—

I think there once existed a patch from the Proxmox guys dealing with the VM state informations. But
apparently did not make it into main-stream.

Kind regards,

Oliver.

This is an automated cleanup. This bug report has been moved to QEMU's
new bug tracker on gitlab.com and thus gets marked as 'expired' now.
