[ovirt-devel] blockcommit and gluster network disk path

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". <disk type='network' device='disk' snapshot='no'> <driver name='qemu' type='qcow2' cache='none' error_policy='stop' io='threads'/> <source protocol='gluster' name='vmstore/912d9062-3881-47 9b-a6e5-7b074a252cb6/images/27b0cbcb-4dfd-4eeb-8ab0-8fda54a6 d8a4/027a3b37-77d4-4fa9-8173-b1fedba1176c'> <host name='10.70.37.28' port='0'/> </source> <backingStore type='network' index='1'> <format type='qcow2'/> <source protocol='gluster' name='vmstore/912d9062-3881-47 9b-a6e5-7b074a252cb6/images/27b0cbcb-4dfd-4eeb-8ab0-8fda54a6 d8a4/d4c23ec6-20ce-4a2f-9b32-ca91e65a114a'> <host name='10.70.37.28' port='0'/> </source> <backingStore type='network' index='2'> <format type='raw'/> <source protocol='gluster' name='vmstore/912d9062-3881-47 9b-a6e5-7b074a252cb6/images/27b0cbcb-4dfd-4eeb-8ab0-8fda54a6 d8a4/f5098809-e719-404b-8d80-3f824f4333a2'> <host name='10.70.37.28' port='0'/> </source> <backingStore/> </backingStore> </backingStore> <target dev='vda' bus='virtio'/> <serial>27b0cbcb-4dfd-4eeb-8ab0-8fda54a6d8a4</serial> <boot order='2'/> <alias name='virtio-disk0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </disk> thanks sahina
