KVM / Qemu Images doesn't work with ceph-fs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi @all,

in an other mail (http://marc.info/?t=130442346600006&r=1&w=2)
I explained my Config. And after two changes in the config file
the ceph-fs works fine :)

Now I want to use image-files (qcow2, raw or img filetype) with KVM.

This doesn't work.

When I do a fresh isntallation / creation with virt-install:


virt-install --connect qemu:///system -n vm18 -r 512 --vcpus=2 -f /ceph/vm18.qcow2 -s 10 -c /tmp/debian-6.0.1a-amd64-netinst.iso --vnc --vncport=5961 --vnclisten=0.0.0.0 --noautoconsole --os-type linux --os-variant generic26 --accelerate --network=bridge:br0 --hvm

The creation of the file works but on installation following errors occur:

When I create a VM with virt-manager the creation of the disk hangs on the following step (creating Domain):

I have no idea whats wrong a

  dd if=/dev/zero of=meineDatei bs=1024 count=10000

works perfect...


I doesn't have any ideas what's wrong.
Creation of a VM directly on the filesystem (without ceph) works fine.



Regards,

Christoph
