Using 1Gb network you would max it out at about 100-105MB/s, What wire/network speed do you have? Or are these tests run locally? Also it is important to use large files containing actual data (not just a files filled with zeros dd if=/dev/zero...) when doing these tests 5-10GB. But this sure...

Just noticed that the online migrations of VM's now also works better. Before it took 16sec to do online migration of my test VM. Now it's done in 10sec. That is with the ssh ciper set to arcfour and using rsync option --protocol=28. I wonder if online migrations would also benefit from using...

Here are the results and conclusion of my extensive testing and optimizations regarding the VM migration process. This shows that with some minor changes we can radically enhance the speed of the migration process and reduce the CPU load of the hosts during the migrations. If we can change the...

The obvious thing here is that using arcfour instead of blowfish reduces the time to migrate in half. the bonus is that it will also use a bit less CPU on the hosts. And the other thing is that if it would be possible to implement a native rsync utilizing rsync daemon directly instead of...

Ok, done some testing. Changed from blowfish to arcfour in those files you mentioned but in my case doing a offline migration of a VM that uses local storage the rsync process is still done over ssh session using blowfish. /usr/bin/ssh -c blowfish -o BatchMode=yes -l root 192.168.10.22 rsync...

Hi and thanks e100 for your reply. I will try changing /usr/share/perl5/PVE/Storage.pm and /usr/share/perl5/PVE/QemuMigrate.pm to see if it works on my end as well. This is exactly what I'm talking about. Arcfour is the fastest of the ciphers even with AMD processors and all the other Intel...

Hi Pasting the very same here since this also applies to v.2. ----- Can anyone tell me how to change the default cipher blowfish to arcfour when doing migrations of VM's? By replacing the cipher we would be able to migrate servers alot faster. I have found that changing the setting in...

I'm just now running tests on beta2 and when I add new NFS ISO storage I cant see any ISO files within the web manager. I can see the files on the consoles on the hosts in /mnt/pve/xxx but web gui shows nothing under content. The status shows enabled, active, usage etc. NFS images shows just...

Hi I would like to see the network configuration on the data center level as well as on the nodes. So that when you run a cluster you can configure the network on the data center level (cluster level). As it is now you have to go through each node and make sure they all have all the same...

Nice, time to do some more testing :D

Nice, I just started to look at R1soft a couple of days ago and now I also find it in this forum regarding proxmox. Are you happy with the R1soft backup solution and how does it work when backing up VM's?

Hi Can anyone tell me how to change the default cipher blowfish to arcfour when doing migrations of VM's? By replacing the cipher we would be able to migrate servers alot faster. I have found that changing the setting in /usr/bin/qmigrate from blowfish to arcfour drastically speed up the...
