Description Lon Hohberger 2007-11-14 19:01:07 UTC

+++ This bug was initially created as a clone of Bug #345871 +++

Currently, the live migration of instances through rgmanager (and Conga), the OS
instance will pause, migrate and then continue.  This can be changed by editig
the vm.sh file and adding "-l" to the migration command.  

We should make "-l" style migration the default to avoid the pause timing out
client connections.

Synopsis: migrate attribute for vm configuration
Possible values: live or pause, default=live

Comment 1 Lon Hohberger 2007-11-14 19:06:04 UTC

e.g.

<vm name="molly" migrate="pause"/>     <--- "xm migrate molly..."
<vm name="frederick" migrate="live"/>  <--- "xm migrate -l frederick..."
<vm name="buster"/>                    <--- "xm migrate -l buster..."

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update
release.

Actually, I do need more info for proper testing.

Should conga auto-detect that hosts are xen vms, and then generate the above
like in /etc/cluster/cluster.conf after only adding the virtual hosts (or
hypervisor)?

Comment 6 Ryan McCabe 2008-05-15 22:35:54 UTC

This is for manual configuration of VM services (to be managed by rgmanager).
The functionality added is letting users choose whether migration type should be
live or pause. You can get to the form via cluster -> [cluster name] -> services
-> Add a Virtual Service. Or you can modify an existing one to get to the same
configuration page.

Comment 7 Brian Brock 2008-05-16 06:21:10 UTC

looks sane across several passes, changing to verified.
