[libvirt-users] Libvirt fails on network disk with ISCSI protocol
Hi,
I am working on oVirt, and I am trying to run a VM with a network disk with
ISCSI protocol ( the storage is on a Cinder server).
Here is the disk XML I use:
<disk device="disk" snapshot="no"
type="network">
<address bus="0" controller="0"
target="0" type="drive"
unit="0" />
<source
name="iqn.2010-10.org.openstack:volume-37fea687-040c-4a88-844c-117d1a90e9b2"
protocol="iscsi">
<host name="10.35.0.20" port="3260" />
</source>
<target bus="scsi" dev="sda" />
<boot order="1" />
<driver cache="none" error_policy="stop"
io="threads"
name="qemu" type="raw" />
</disk>
I get the following error:
libvirtError: internal error: process exited while connecting to monitor:
2017-08-02T14:38:58.378430Z qemu-kvm: -drive file=iscsi://
10.35.0.20:3260/iqn.2010-10.org.openstack%3Avolume-37fea687-040c-4a88-844c-117d1a90e9b2,format=raw,if=none,id=drive-scsi0-0-0-0,cache=none,werror=stop,rerror=stop,aio=threads:
Failed to parse URL : iscsi://
10.35.0.20:3260/iqn.2010-10.org.openstack%3Avolume-37fea687-040c-4a88-844c-117d1a90e9b2
It seems that the ':' character got changed on the way to %3A.
Any suggestions on the root cause of this issue?
Thanks,
Fred Rolland

Even though our documentation states: If not specified, the default LUN is zero. http://libvirt.org/formatdomain.html#elementsDisks Maybe something changed in QEMU or libiscsi since that document was written?

Re: [libvirt-users] Libvirt fails on network disk with ISCSI protocol
Thanks, it was the issue. I guess the documentation should be updated. Thank you for your help !
