But yeah, without the -c storage:///system one won't see the results because 'npools == 0' when virCapabilitiesFormatStoragePoolXML is called from virCapabilitiesFormatXML unless it's the storage driver URI.
Err, don't you mean "virsh pool-capabilities".
pool-capabilities takes a different path ending in virStoragePoolCapsFormat as opposed to capabilities which ends up in virCapabilitiesFormatXML
The "capabilities" command is exclusively for the virt driver usage, not storage.
# virsh version Compiled against library: libvirt 6.6.0 Using library: libvirt 6.6.0 Using API: QEMU 6.6.0 Running hypervisor: QEMU 5.0.50
# virsh -c storage:///system capabilities
[as above]
This work is/was done Jan/Feb 2019 - Perhaps I'm only getting asked (again) about it now as a result of some downstream documenting :-/. Far too long ago for me to recall why both options were done.
But separable enough in commit 05fe03505a to be undone.
Ohh, that's bizarre. I don't see the point in reporting the storage stuff in "capabilities", as it is a subset of what you're reporting in "pool-capabilities". We certainly shouldn't encourage anyone to use the "capabilities" stuff for storage, so any docs should direct people to "pool-capabilities" Regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|
