Hi, Someone already use xen as production server? For example: 3 domains (mail, proxy and web server). And what about stability? Regards, Marlon _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hi Marlon, I am doing just that, including both production envoironments and development/test envoironments on the same machine. I have has zero problems running this under Xen.

For an extreme example see: http://wiki.xensource.com/xenwiki/CoolConfigurations Also note that the community sites wiki.xensource.com, xenbits.xensource.com, lxr.xensource.com, lists.xensource.com are all hosted on Xen 2.0. Lots of people are using 2.0 in production, 3.0 is a little off production ready at the moment - give it a few months before deploying for serious production use.

Hi Marlon, Here we use the Xen in all our servers. Firewall(Xen0) with its respective domains (smb, web, app, etc). Having the same stability of a common Linux.

I''ve Been running Xen on a production server for about 5 months now. I have a dedicated mysql server domU a dedicated mailserverver domU and I virtualhost off of the dom0 at present(migrating this to a domU soon). So far things have been stable and its working out well. Just fyi - this email is being sent from the mail domU :) Cheers, John Fairbairn> On 7/27/05, Marlon Cabrera Oliveira <marlon@mrgnetwork.com.br> wrote: >> Hi, >> >> Someone already use xen as production server? >> For example: 3 domains (mail, proxy and web server). >> >> And what about stability? > > I''ve got four machines running Xen 2.0.

Weve been running Xen for a bit now, and it has been very stable. The servers are running cooler, and with a lower load average, as compared to other virtualization setups. Were running mulitple linux domU''s per server, under a variety of loads, and the vps''s are very responsive. Xen is quite ready for production. -Tim -- Timothy Doyle CEO Quantact Hosting Solutions, Inc. tim [at] quantact dot com http://www.quantact.com Nate Carlson wrote:> On Tue, 26 Jul 2005, Marlon Cabrera Oliveira wrote: > >> Someone already use xen as production server? >> For example: 3 domains (mail, proxy and web server). >> >> And what about stability? > > > I''ve been using it for at least 6 months (don''t recall exactly when I > started) for my personal hosting needs.

Well, I guess it depends a lot on what version do you use. I used to run the stable version and was mostly happy with it, I had some random lock-ups, missed interrupts from the hard disk, which I cannot say were related to Xen or were a hardware problem. Now, I''m having a terrible time the the FC4 rpms, which I understand are based on Xen unstable. Basically I''ve given up on making Domain_0 to communicate with the guest domains via the network. I tried every possible network setup, routed, bridged-new, bridged-old, all to no avail. I ended up with the old style bridged setup because it was the last one I tried. Everything else works, I evenhave a DHCP server in one of the guest domains, which serves machines on a different subnet from the rest of the machines, and everything works fine (as it was before), but I cannot, for instance, ssh from Domain_0 to a guest domain. I can ssh to anyother machine and ssh back to the guest domain from there, and it works fine, only the direct connection fails, it hangs never completes. I even used ethereal to try to figure what was going on, but couldn''t find anything, the connection just hangs there waiting for a packet that never arrives. The guest domains cannot connect to Domain_0 either, which is unpleasant because on my setup I had some common services (DNS, nfs, etc.) running on domain_0. I had to move this inside a guest domain. Also, there are some issues with domains failing to shutdown properly, and I''ve had one or two or three instant reboots when xm destroying these wedged domains. NOT that I''m complaining, mind you, it''s not called unstable for nothing :) Apart from that, it''s working really fine. I don''t know if it is a psychological effect of all the trouble I went through, but on one of the guest domains that uses the disk a lot (a gentoo instalation :) it seems *a lot* faster. BTW, I ''upgraded'' because I wanted to try GFS, and I thought it would be easier to use a redhat kernel that had all the stuff already patched in. I''m not so sure right now... --- tim Doyle <tim@quantact.com> escreveu:> Weve been running Xen for a bit now, and it has been very stable. > The servers are running cooler, and with a lower load average, as > compared to other > virtualization setups. > Were running mulitple linux domU''s per server, under a variety of > loads, > and the vps''s are very responsive.
