Hi, I want to run a i386 domU on my AMD64. I created a LVM partition with Debian Sarge i386 on it, and set everything up. Now for the compilation of the kernel for i386. In "linux-2.6.12-xenU/" , make ARCH=xen menuconfig, i did: Processor Type (X86) (which was selected, and compiled with X86_64 before) Processor family (Opteron/Athlon64/Hammer/K8) [*] Generic x86 support if

When does vif0.0 get created? Is there some shell magic?

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

I would like to run multiple copies of an application on a PC with multiple remote dumb clients. It would seem to me that running Xen would be a sub-optimal solution as I would need a copy of the OS running for every copy of the application, but I was wondering whether a subset of Xen or Xen techniques could be used. There are 2 barriers to running multiple applications with remote access: -

Hello I use XEN 3.0 in debian sarge. I have a domU1 for routing and firewall. This domU1 use 2 network interfaces which is on a bridge ''gate'' and the other on bridge ''lan''. dumU2 use one interface (eth0) on bridge ''lan''. Then I make a ping out of domU2 to www.debian.de so I get no answer. The name isn''t resolved. A ping to IP of

Hello, I have running xen over a debian server (debian sarge). Now I would like to configure a domU with redhat (AS 4), do you now any way to install it? -- Angel L.

Has anyone done any performance profiling for Xen on different platforms? I''m wondering if the big (50%+) memory latency advantage the Opteron''s have over the Xeon''s makes a big difference in the context of a Xen host with multiple active guest domains. Particularly at the moment I''m considering the 2-way situation with the SunFire v20z vs the Intel SR1400JR2.

Hi, I''d be very interested to hear: does anyone have a stable working amd64 machine (in 64bit mode)? if so, which kernel do you use, and which version of xen / hg tree do you use? linux-2.6-xen.hg compiles fine over here, but reboots during boot. so fast I can''t see anything. (sorry, my laptop has no serial port. so I can''t capture a log file.) 2.6.16-rc4-git8 plus

If independent_wallclock is set to 0, then that means running ''date'' in the domU should provide exactly the same answer as running ''date'' on dom0, right? But this isn''t happening for us. The domU''s are all running minutes behind the dom0 - in one case 16 minutes behind! dom0$ date Tue Jun 27 14:23:01 BST 2006 domU-a$ date Tue Jun 27

Hello everyone, I have been able to get windows xp to run under a virtual machine, but i cannot get any network access. My desktop is connected to a university network, and we are only given 1 ip address. so i understand i have to use routing instead of bridging, right? i have commented the two lines for bridge and enabled routing in /etc/xen/xend-config.sxp next i inserted a line: vif

I set up a 3.3 gluster volume for another sysadmin and he has added it to his cluster via automount. It seems to work initially but after some time (days) he is now regularly seeing this warning: "Too many levels of symbolic links" $ df: `/share/gl': Too many levels of symbolic links when he tries to traverse the mounted filesystems. I've been using gluster with static mounts

hi, guys: Today when i typed "mount " command on the server and found this message: .. ... 192.168.9.252: /home/share/tmp on /net/tmp/share type nfs ( rw, bg, soft,rsize=8192,wsize=8192,addr=192.168.9.252) 192.168.9.252: /home/share/tmp on /net/tmp/share type nfs ( rw, bg, soft,rsize=8192,wsize=8192,addr=192.168.9.252) 192.168.9.252: /home/share/tmp on /net/tmp/share type nfs (

Peter, we found that nfs over udp will corrupt data under very extrem load, there is no way to fix it due to the way how UDP works. TCP will not have these problems. I also wonder why the package size is only 1k. Everyone who wishes a slow connection can pass the desired options via the kernel cmdline. Everyone else prefers probably the fast mount. The defaults should look more like that: ---

Hello all, I have observed a problem with a diskless PXE client I am attempting to configure. PXE/NFS/DHCP/TFTPd server is running CentOS5.1 and the Diskless workstation's root and kernel was extracted from a CentOS5.1 (custom kernel due to setting to enable Root File System support). Problem: When the diskless client boots and logs in I notice that my root user is being squashed, even if I

I have this NFS client that used to be on Red Hat 7.3. For mounting user home directories I used this line in /etc/auto.master file: /home yp:auto.home rw,rsize=8192,wsize=8192 Moved the box to CentOS 4... The format of the file changed, so I attempted something like this: /home -rw,rsize=8192,wsize=8192 yp:auto.home No habla. Doesn't work. The rsize and wsize options seems to be
