Hi,
is there any documentation regarding all allowed settings in the vdsm.conf?
I didn't find anything related in the rhev docs
that's a question for vdsm mailing list - cc-ing…
the vdsm.conf has a description for each parameter…just search for all containing "migration":) we do want to expose some/most/all of them in UI/REST eventually, the "migration downtime" setting is there now in 3.4, but others are missing
Thanks, michal

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) _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
