Hello,
Using ONE 4.2 on Debian wheezy.
I just upgrade the qemu and libvirt to wheezy backports to solve bad
interaction between emulated card and guest kernel[1].
Now I can not boot VMs with PERSISTENT images.
I found a thread[2] on the mailing-list which looked like my problem, I
made the checks without success.
My environment:
---
OS: Debian Wheezy
qemu-kvm: 1.7.0+dfsg-2~bpo70+2
libvirt-bin: 1.2.1-1~bpo70+1
ONE: 4.2, from OpenNebula deb packages
Datastores:
- 0: local disk of each host
- 1: NFS TM_MAD=qcow2
Test 1:
---
IMAGE_ID=114
PERSISTENT=NO
The VM boots fine
Test 2:
---
IMAGE_ID=114
PERSISTENT=YES
The VM FAILED.
The only difference is the use of a symlink, does someone know any issue
with libvirt/qemu to use disk images though symlink?
Regards.
