Hello all fellow CentOS users!
I have a working xen setup with 3 paravirt domUs and one Windblows 2003 fully virt domU.
There are to virtual networks.
As far as I can tell in the paravirt Linux DomUs I have gigabit networking, but not in the fully virt Windows 2003 domU....
Is there a setting for this, or is it not yet supported?
I run xen-3.0.3-64.el5_2.3
Kind regards, Coert

Both networks should be available in the Linux and the Windows domU's. Could you send the Xen configfiles for the domU's ? They should list to which network each domU gets attached.

That's not on the dom0 side, but directly in the w2k3 domU .. : you'll get *bad* performances (at IO and network level) if the xenpv drivers for Windows aren't installed .. Unfortunately you will not be able to find them for CentOS. (While Upstream have them of course)

I see on google that no one really knows when they will make xenpv available in CentOS....
But I will be able to live with the performance... I intend on making the w2k3 server a domain controller and print spooler. Any warnings I should heed in this respect?
I am using Samba as a file server.
Kind regards, Coert

well, how did you reach that conclusion ? Essentially, you get your credit card out and pay Citrix for the drivers. Considering they use CentOS within their development / testing process I am quite sure they have the right stuff required for the Windows DomU hosted on CentOS Dom0

I will definitely look at such an option, but I do not want to go custom with my CentOS implementation, and I am only going to use the windows 2k3 domU as domain controller and print server, so if it does not negatively impact speed of other PV domUs then I can live with 100Mbps and slower I/O
But I am definitely keeping a lookout for when xenpv comes out for CentOS
Thanks, Coert

ok, so you seem confused about what Fabbian said to you - its the windows Xenpv drivers you need, CentOS already has all that stuff included in there.

I'm elevating myself from "noob" to "noob with scars." I'm not one to ask a lot of questions if I have time to find out on my own.
I now know at least a half dozen ways to hose a solid CentOS Xen install. That's a good thing, I learn from mistakes. Like forgetting to actually completely configure priority statements in the repo confs.
In the past I have used yum protect-base, but about a year ago or so I switched to yum priorities because it seems a bit more granular.
Is there a recommended preference on CentOS Xen installs? I'm pretty conservative now and won't go near Plus or Contribs, I do have Convirt repos in and it looks like they pulldown a couple dependencies from RPMForge (paramiko and socat).
I don't plan on anymore repos, but am wary enough to want to nail my last install down.
Any prefs here for CentOS Xen? Yum Protect-base or Priorities?
Just a quick saying to encourage you: wisdom is knowledge learned through mistakes. Building things is good, but breaking things let's you learn how to build better things.

I sure wish that was true in my relationships.

Personally, I would go with priorities because it gives you more control.
I'm currently in the process of switching to priorities because of packages from external repos replacing the stable ones that come with CentOS even though I was using protectbase. I'm not entirely sure this is what was causing my reboot issues on the Xen boxes that I run but it certainly could have been a factor.

I have installed gplpv_fre_wnet_x86_0.10.0.69.msi on Xen 3.1
It works perfectly so far!
Weird thing though, rpm tells me I have xen-3.0.3-80.el5_3.2 but xm info gives me this: (is this Xen 3.1?)

Another question: in my windows DomU the old realtek RTL8139 emulated network card driver still shows, and the Intel 82371SB Bus master IDE controller. They all have a "Device can not start" error. I have uninstalled them in Device manager, but when I reboot they show up again, and event viewer also has a few entries on the network cards not wanting to come up.
on the wiki ( http://wiki.xensource.com/xenwiki/XenWindowsGplPv ) they want you to remove the vif entry. But I need two virtual networks to the DomU.
I have removed the ioemu part, but no difference.

You are in luck. With that configuration I got BSOD when I booted Windows. I had to install Xen 3.3 available at http://www.gitco.de/repo/.

xenpv hides ide and scsi controller detected by Windows, to avoid problems with double access by two drivers to the same disk. The drawback is that the configured cdrom is not accessible. I think this will solved with Xen 3.4 and qemu capabilities to hide devices ??
on the wiki ( http://wiki.xensource.com/xenwiki/XenWindowsGplPv ) they want you to remove the vif entry. But I need two virtual networks to the DomU.

Configure each interface vif: vif = [ "type=netfront,mac=XXXXXXXX,bridge=XXX", ]
