[libvirt-users] blockcommit and gluster network disk path

[Sahina Bose]

Hi,

I'm running into problems with blockcommit and gluster network disks -
wanted to check how to pass path for network disks. How's the protocol and
host parameters specified?

For a backing volume chain as below, executing
virsh blockcommit fioo5
vmstore/912d9062-3881-479b-a6e5-7b074a252cb6/images/27b0cbcb-4dfd-4eeb-8ab0-8fda54a6d8a4/027a3b37-77d4-4fa9-8173-b1fedba1176c
--base
vmstore/912d9062-3881-479b-a6e5-7b074a252cb6/images/27b0cbcb-4dfd-4eeb-8ab0-8fda54a6d8a4/d4c23ec6-20ce-4a2f-9b32-ca91e65a114a
--top
vmstore/912d9062-3881-479b-a6e5-7b074a252cb6/images/27b0cbcb-4dfd-4eeb-8ab0-8fda54a6d8a4/027a3b37-77d4-4fa9-8173-b1fedba1176c
--verbose --wait

gives "error: invalid argument: No device found for specified path".
