Greetings,
I am using RHEL 5 update 1 and I am having trouble getting "real"
live migration to work in a cluster environment.
When I do this on member2:
# clusvcadm -M guest1 -m member1
The guest1 is first suspended on member2, its memory copied over to
member1 and then started on member1. With several gigabytes of RAM in
the guest, this amounts to an outage of more than one minute (on gigabit
ethernet), losing network connections etc..
When I do this on member2:
# xm migrate guest1 member1 -l
The guest1 continues running while its memory is being copied over to
member1, there is only a brief pause at the end of the copying process.
It looks like as if clusvcadm did migration without the "-l"
parameter...
Is this behaviour configurable or is this not supported by clusvcadm in
RHEL 5 update 1 yet? How do you solve this issue in your cluster?
Thank you very much for any advice.
Best regards,
Daniel Zavodsky
