Description SATHEESARAN 2013-10-09 11:32:31 EDT
Description of problem:
QEMU now provides the efficient way to create images (raw,qcow2) on glusterfs volumes directly using libgfapi and not using fuse mount.
(e.g) qemu-img create gluster://gluster-server/vol-name/file1.img 30G
      qemu-img create gluster://gluster-server/vol-name/dir1/file1.img 30G

But there are no options currently available to make use of such an image available in glusterfs volume(using this qemu+glusterfs driver ), for the creation of VM

This bug is raised to add such an option

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:

Actual results:
No option provided for making use of qemu+glusterfs driver, for the creation of VM

Expected results:
There should be an option to make use of qemu+glusterfs driver

Additional info:
qemu-system-x86_64 has option called "--file", which expects the argument in the form of, "gluster://<gluster-server-host>/<gluster-volume-name>/[<dirname>/]filename"

Note: directory name is optional
Comment 1 Daniel Berrange 2013-10-09 11:35:41 EDT
virt-manager does not want to ever run any qemu tools directly. This requires adding support for a gluster based storage pool in libvirt first.
Comment 2 Cole Robinson 2013-10-09 12:01:17 EDT
Well there's domain <disk> support for gluster volumes, right? I figured that's what the initial IRC query was about. But yes if you want virt-install to create a new volume and not just use an existing one, it will require libvirt patches as well.
Comment 3 Cole Robinson 2014-02-01 10:52:05 EST
Also, we should at least make sure virt-manager UI doesn't blow up or look awful when it sees a network disk

Another bit, from the duped bug, is allowing HTTP cdrom installs. I don't think we should add an explicit new mode for it, but maybe we can make virt-install/virt-manager 'just work' if passed an HTTP iso path as CDROM media. Something to explicitly test at least.
Comment 6 Cole Robinson 2014-12-10 14:02:42 EST
Upstream virt-install supports:

--disk $URL

for gluster, http, etc. It should 'just work'. It also allows explicit building like:

--disk source_protocol=gluster,source_name=...,...
