Hi,
is there any documentation regarding all

I didn't find anything related in the rhev docs
that's a question for vdsm mailing list - cc-ing...

Betreff: Re: [Users] Migration failed (previous migrations succeded)
Now I' getting serious problems. During the migration the VM was
doing a rather slow download at 1,5 MB/s. So the memory changed
by 15 MB per 10 seconds. No wonder that a check every 10 seconds
was not able to see any progress. Im scared what will happen if I
want to migrate a medium loaded system runing a database.
Any tip for a parametrization?
Markus
what's the bandwidth? default is up to 30MB/sec, to allow up to 3 VMs to
migrate on 1Gb without congesting it.
you could raise that if you have 10GB, or raise the bandwidth cap and
reduce max number of concurrent VMs, etc.
My migration network is IPoIB 10GBit. During our tests only one VM
was migrated. Bandwidth cap or number of concurrent VMs has not
been changed after default install.
Is migration_max_bandwidth in /etc/vdsm/vdsm.conf still the right place?
probably
And what settings do you suggest?
well, to begin with, 300MB/sec on 10GE (still allowing concurrent
migrations)
