Hello,
I’m planning to install Oracle 11g on a VM inside oVirt. I already knew
about the licensing hell of running Oracle 11g on a virtualized environment.
The question is about snapshotting Oracle 11gb when the VM is running. Is
this supported?
Supported by ovirt, not sure that by Oracle :-)
For example, on VMware and XenServer there’s the quiesce option to
make
the filesystem, with a little help from the guest agent, to be in an a good
state for snapshots. But in oVirt, how this is handled? If supported, which
operating systems are compatible with the feature?
In ovirt we use libvirt's virDomainFSFreeze[1] and virDomainFSThaw[2]
to freeze guest file systems during a snapshot.
On the guest side this uses qemu guest agent (which you must install),
to run application specific scripts when freezing or thawing the file
systems[3].
I guess oracle or someone an provide scripts to hook to qemu-guest-agent,
or you can write them yourself base on oracle documentation.
