ocf:heartbeat:VirtDomain extension to use qemu+ssh with a normal user
|
|
Hello,
it is possible to use an user name to migrate a domain via qemu+ssh?
I checked the function VirtualDomain_Migrate_To but I did not find any
hint, how I can migrate a domain with a normal user.
So I extend this agent a little bit. Shure, this is a quick'n'dirty hack
and I can not promise, that this extension will work in all cases, but
this solves my problem (ssh login/migration via root is not
possible/allowed).

< remoteuri=$(echo ${OCF_RESKEY_hypervisor} | sed -e
"s,\(.*\)://[^/:]*\(:\?[0-9]*\)/\(.*\),\1${transport_suffix}://${target_node}\2/\3,")

Now I can define a primitive like this:
primitive resVirt_ubuntu64bit ocf:heartbeat:VirtualDomain \
meta allow-migrate="true" \
params config="/etc/libvirt/qemu/ubuntu-64bit-2.xml"
migration_transport="ssh" user="polnik"
... and I can migrate a domain via ssh with an normal user.
btw: Is there any new version planned for this agents in the near
future, i.e. to use follow migration options:
migrate-setmaxdowntime
migrate-setspeed
Best regards,
thomas.
