Hello ,
I have a configuration with xen with 2 domu .
One domu have a nfs server , Other have a ftp server .
When i try to write a big file to the nfs server
( so i generate a big traffic , on network and on disk )
dom0 and domU''s become inaccessible via network .
I have the same problem , via ftp when i put a big file .
On the console , i must make ifconfig pethX down/up to restore the network .
I''am using xen-3.0.3-0-4 on debian - etch .

Is your file transfer as large as 2 GB? While NFS is very useful for lightweight file transfers, it gets..... awkward for high-speed trasnsfers. Also, which version of NFS are you using? Have you optimized it at all? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

After a few hours, I''d loose total network connectivity unless I stood at the console and pinged something. I updated my e1000 driver from sourceforge and haven''t seen the issue since.

typically when i tried to synchronize a directory which contains recents photos
on the nfs server .
Each file 2 MB , many files .
Via ftp or via nfs or via rsync , the symptoms is the same ,
all domU are inaccessible .
I must use the compression on rsync or the option bwlimit , to limit
the traffic .

Hi, I have a similar problem when running backups on my VMs using rsync (backuppc actually, but it uses rsync). First thought was to limit bandwidth, but they are bridged on 1000Mbit interface and backup goes as slow as 1 MB/s due to poor software of NAS that contains backup - so I don''t know if there is a sense in limiting rsync to, say 10Mbits while it uses 8 MBits at most...
