Old Live migration

[vitor costa]

In 1.4 the new live migration to KVm works only with shared storage. The old live migration with rsync , freeze, rsync will no more possible ? Products like Hyper-V have various migrations options with diferents down times to diferents configurations... Maybe Proxmox can resurect this procedure to live migrate local estorage vms.

The openvz containeres still not suported in shared storage ? if so the live migration is not possivle right ? I know in 1.3 not working anyway....

Sure. Someone needs to implement it (low priority for us).

live migration work quite well with openvz (besides some bugs in the openvz kernel).

I guess you missunderstood something. I said live migration works. I did not say that you can use shared storage with openvz (live migration for openvz works without shared storage using 2 phase rsync).

I see....

I Try now to migrate a VM-VZ. I create a new one, CentOS template and receveive this:

/usr/sbin/vzmigrate --online 192.168.2.3 106
OPT:--online
OPT:192.168.2.3
Starting online migration of CT 106 to 192.168.2.3
Preparing remote node
Initializing remote quota
Running: /usr/sbin/vzquota init 106 -b 8388608 -B 9227468 -i 1600000 -I 1760000 -p /var/lib/vz/private/106 -e 0 -n 0 -s 0
Running: /usr/sbin/vzquota show 106
Running: /usr/sbin/vzquota on 106 -r 0 -b 8388608 -B 9227468 -i 1600000 -I 1760000 -e 0 -n 0 -s 0
Syncing private
Live migrating container...
Error: Failed to dump container
VM 106 migration failed -

Then i create another one with Ubuntu template... same result...


Some months i see you talk about the openvz kernel problens.. the migration work ok in 2.6.18.... and so...

In what situations vz live migration works in PVE ? (i never see its happen, i tried 1.3 with same results)
