This affects oVirt Node a bit (which is why I've got an interest) but is
also relevant to vdsm running on vanilla hypervisors like F16.
Two decisions we need to get acks on:
1. Location of local storage for vdsm is /rhev in the RHEV product.
Suggestion is to change this to one of:
/ovirt
/var/lib/ovirt
/opt/ovirt
2. Naming of the management interface that vdsm uses. Right now in
RHEV product, vdsm renames the mgmt interface to 'rhevm'.
Suggestions fall into a few categories (thx to danpb for putting
these options together)
- brN, where N is assigned incrementally from 0. eg
br0 containing eth0
br1 containing eth7
br2 containing eth42
br4 containing vlan7.3 for VLAN 3 on eth7
- brN, where N is chosen based on the last digit from the
physical interface enslaved eg
br0 containing eth0
br7 containing eth7
br42 containing eth42
br7.3 containing vlan7.3 for VLAN 3 on eth7
- brDEV, where DEV is the name of the physical interface
breth0 containing eth0
breth7 containing eth7
breth42 containing eth42
breth7.3 containing vlan7.3 on VLAN 3 on eth7
- brNET, where NET is a logical name of the network
brmgmt containing eth0 as the management LAN
brguest containing eth7 as the guest <-> guest LAN
brinet containing eth42 as the guest <-> internet LAN
briscsi containing vlan7.3 for the iSCSI storage LAN
My personal vote is to use:
/opt/ovirt rather than something off of the root filesystem, since this
will fit in with how we're going to enable plugins and writable portions
of the filesystem in oVirt Node anyhow
I also vote for interface naming like brNET, so brvdsm. Keeping in mind
that the mgmt interface will not always be a bridge in the future, so if
the mgmt interface is _not_ a bridge, then 'vdsm' by itself would be a
good name. The br prefix should only be used if/when the vdsm interface
is also a bridge.
That's just my 2c, discuss on list and let's see if we can reach a quick
consensus so we can make fwd progress.
Cheers,
Perry
