[pve-devel] qemu-img iscsi initiator name

[Alexander Schmid]

Sorry,
i totally missed that this was discussed in Feb. 2016 on the list.

Now there should be support in qemu, not only for passing an 
initiator-name but also CHAP Authentification:
https://patchwork.kernel.org/patch/9466379/

If there is an interest to get this sorted-out i can figure out how the 
cmd should look for qemu-img / qemu-mirror and do my best to create a 
set of patches.

I think multiple parts in QemuServer.pm would be affected.

Currently an iscsi-url is returned as path and passed to qemu-xxx commands.

So, the source and destination storage plugins need to at least tell if 
they use iscsi and provide a config to use in with qemu commands.

Not sure where the best place for an implemantation is.

My idea would be a flag in the storage-config if the plugin uses iscsi 
at all plus a helper sub in StoragePlugin.pm that gives back a set of 
suitable values for the qemu commands.
