Hi Jan, On one of the systems connected to Internet (99.9999% of the systems are not here) is doing mirroring of gwdg.de. So my nfs-server (currently in dom-0) hosts the repo's for SuSE, ubuntu, centos, fedora and *BSD. The real rsyncing is done in a dom-U, but i found, if i do not apply rate-limiting with rsync, it will destroy the dom-0, causing oopses and panics. When reported (both here and on the SuSE-list), i got the reply that i should not have done it in the first place. Other dom-u's are http(s) servers, acting as installation-servers or VPN-end-points. So i could rebuild the lot, with the dom-0 doing only xen-stuf, and have the nfs-functionality transferred to a dom-U, but only if it solves anything, otherwise it's a waste of time...

Generally speaking this works well although we do occasionally experience NFS problems (dom0-domU). The rule of thumb indeed seems to be to avoid running much in dom0 so dom0 can concentrate on I/O. I think it depends on what you plan to do with dom0/domU. groet, Jan J.Witvliet@xxxxxxxxx wrote: > > Hi all, > > A while a go, I was told that it is advisable to run as little as > possible services in the dom-0. > Is it safe / stable / advisable (whatever) to have these functions > (nfs, smb, rsync, etc) in a dom-U ? > > Kind reagards, Hans > > Defensie/CDC/IVENT/Research en Innovation Centrum Ing J.
