Well, after the 3.2 update, just about all of our problems were fixed. We applied it within the first week of April. But I think it may have introduced a new issue. We have a Windows Small Business Server 2003 Std R2 server that we use for VPN connections. It is a virtual machine on our XenExpress server. Ever since the update, we can no longer connect to other VMs on our XenExpress server over the VPN. We can connect to other systems in the office over the VPN, but not any other VMs on the XenExpress server. The VMs can communicate with eachother fine via IP. It just seems to be the VPN connections that are unable to communicate with the XenExpress VMs. I have looked at the firewalls and I don't think it is a firewall issue.
Again, it seems that it was clearly introduced at the time that we upgraded from 3.1 to 3.2.
We are VERY pleased with the XenExpress server overall, but this little issue would increase our productivity, and allow us to NOT move backward from the solutions and technology we've been using. XenSource is of course a big leap forward in other ways. Did I mention that we like it?? :-)

We are really enjoying using XenExpress on our new Dell PowerEdge 1950 Quad-core Xeon. It's extremely fast now with 4 virtual servers running on our Xen server. I am ready to plop down the $700.00 to purchase the XenEnterprise version, which will allow us to have unlimited VMs, but before I do, I need answeres to few problems we've experienced.
1.) Xen Virtual Machine crash - We have 2 linux VMs running Debian Sarge, and 2 Windows VMs, one running Windows Small Business Server 2003 Premium R2, and the other running Server 2003 R2. I use a Mac, and so I connect to the Server 2003 R2 VM via RDP to do a lot of Windows work. One of the things that I do there is administer the Xen server. We have the Xen Administration program loaded onto that VM. It generally works fine administering the VMs that way. However, about an hour ago I was logged onto our Server 2003 R2 machine and running the Xen Administration program, when suddenly my RDP session stopped working. I reconnected about a minute later, only to find that the VM had rebooted. Just a moment later, a colleauge mentioned that the other Windows VM had just restarted unexpectedly. Upon logging back into both, we were prompted with Microsoft's window which asks why the computer was unexpectedly shut down. I then logged into the linux VMs, and ran the uptime command to find that one reported being up for over 4 days, and the other over 5 days. So only the Windows servers were rebooted. I SSH'd into the Xen Server & checked out the /var/log/messages & /var/log/xen/xend.log log files, as well as others that I thought may give helpful information. Those two were the only ones that really seemed to tell much about the unexpected Xen problem. I have a pretty good hunch as to what caused the problem with the server I was using (Server 2003 Standard R2), but I have no idea why it took the 2nd Windows server down with it. (By the way, the VMs are running fine now).
Here's exactly what I was doing at the time of the VM crashes:
I was connected to the Windows Server 2003 Standard R2 via RDP on the console connection. And I think the console fact is the important one here. The reason being is because the last thing I did before the servers crashed was open the Xen Administration program, select the Server 2003 Std R2 VM from the list in the upper-pane, then click on the "Graphical Console" tab down below. I am thinking that because I was remotely connected to the server's graphical console via RDP, the Xen Administration program didn't like the idea of me viewing the graphical console from it, from within the graphical console. I've had similar issues w/ VNC connecting to the local host, only to get an endless loop of embedded screens. Hmmm. This is absolutely the only reason why I can imagine that this happened.
So, perhaps for now, a lesson learned is to be more careful with that. But perhaps in the meantime, XenSource can implement an if-then statement in their software to check before hand as to whether allowing their software to do something (try to do, anyway) is going to cause problems.
I think the big problem here however, is that my 2nd Windows VM was taken down with the other. I think this is totally unacceptable. Just a passing detail that may help in solving this problem is that one or two other times, I have had problems connecting to the Xen server from the Xen Administration program, so I SSH'd into the Xen server & restarted the XenAgentD process (service xenagentd restart), only to find that it also killed & restarted my Windows VMs unexpectedly, while leaving the linux VMs unscathed.
As previously stated, I am ready to pay the $700.00 for XenEnterprise, but not until I get a good answer to what caused this, and get a permanent fix.
As far as I am concerned, I am very excited about Xen. I love to see Open Source software actually make some money and develop into a strong competing business to proprietary software companies. That is why I chose Xen over VMWare for virualization.
I don't think that most people using Xen have problems like this. The very fact that Xen is marketed & often reviewed as a strong competitor to VMWare all the more confirms to me that this is probably not a common problem. Also, the founder of XenSource (Ian Pratt), stated in July 2006 that there were very few outstanding bugs in Xen at that time (this was in a PDF titled "The Xen Roadmap"). And I'm thinking that coming from this guy being a very experienced professional programmer, this probably refers to issues that are so small that I probably wouldn't even notice them (although I may be overzealous here).
Also, HP and I think IBM are strongly backing Xen, and sell servers preloaded with it. HP has published whitepapers in conjunction with XenSource stating how great Xen is and posting benchmarks running on their systems. I really don't think they would do this, if my problems were commonly experienced.
So what I'm trying to say is that I don't think that Xen is a buggy solution that shouldn't be used on production servers. We've actually been very, very impressed with it overall. But there is obviously something wrong here, and I need to be reassured that we're making the right decision by virtualizing with Xen, before I commit to invest in it. And once that we really are convinced that it is the right way to go, we will continue to invest in it, and work to steer our clients the same way. Once that we commit ourselves, then we want them to be successful, and so will gladly pay them in doing our part to help them have the financial resources needed to continue to improve & be successful.
As for now, I am posting this with a request for help. I have placed the relevant portions of the log files here: http://www.kgotsi.com/static.php?page=s ... s-20070326
Please provide assistance, and also contact someone in the Xen sales division and let them know that you are sending them another buyer, whose problems you just fixed.
Thanks a lot!

I haven't had any bad experiences with BestBuy. But it seems that others have. I have read through the following post (what I deemed to be the "meat" of each of the 25 pages). Needless to say, others have had some pretty painful experiences with BestBuy. And I doubt that BB is the only company that has complaints & "horror-stories" like this one. I actually appreciate BestBuy in a way, because being a network consultant, sometimes I need a part/software fast, and they have a pretty decent stock. I must say that I think that their Dynex & GeekSquad lines of hardware are junk (I did get the run-around on a $55 external HD enclosure, which I finally just gave up on, even though it was still under the manufacturer's [Dynex/BestBuy] warranty). I've had far better results dealing with warranty claims with brand-name products. WalMart's array of stocked computer/soho network merchandise continues to grow, and I appreciate this good & sometimes cheaper alternative to BestBuy. Anyway, I'm not anit-BestBuy, but this person's experience has definitely caused me to have some serious second thoughts about buying their extended warranties (PSP's).
