I tried netperf / netserver with Dom0 / DomU, but I could''nt get a correct NW traffic with xentop. Is there anybody could help me? At Host1''s Dom0, run netperf -H VMIP At Host2''s DomU (with VMIP named TTVM), run netserver At Host1, run xentop this way ->"xentop -n -b -d 1" At Host2, run xentop this way->"xentop -n -b -d 1" In Host2''s

Hi, I know this may be very basic question but I need some help . Actually I installed VM using the Xen Administrative console. Now I need to change the configuration file as I need to passthrough (using the pci-hide) a SCSI contoller from Dom0 to DomU. But I couldnot find the configuration file. Where can I find the Configuration file for this DomU? Actually I added the

Hi guys, I''m running a freenas domU (FreeBSD 8.3 based, ZFS v28, 2 vcpus mapped to the same HT capable core) to serve storage for all purpose including other domUs running on the same host. I did some study to understand how well it works and the result is kind of confusing. In summary, the network performance between domains on the same host is worse than expected. And NFS service to

Was setting up 2 domUs on the same xen machine. Is there any benefit in using the same bridge vs. two separate bridges (one for each domU) incases where we are interested in only domU-domU network traffic? What will be the preferred configuration? thanks in advance, harish _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

Dear, "Xenoppix-x86-64(Xen3.0.2+KNOPPIX-x86_64-5.0.1) CD size" is released. http://unit.aist.go.jp/itri/knoppix/xen/index-en.html Xenoppix-x86-64 exploits latest CPU (Intel Core2 Duo and AMD Athlon64). * Xenoppix-x86-64 boots both X86 and X86_64 linux kernel on HVM of Xen. * Xenoppix-x86-64 looks like KNOPPIX but all packages are replaced for X86_64. * Xenoppix-x86-64 also

Dear all, I wanted to know the processes running inside domU from dom0. Is it possible? if yes,how to know? Thanks & Regards, Yashwanth _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hello, I noticed that the CPU% reported by xentop appears to be too high. With dom0 idle xentop is reporting between 14-17% CPU utilization while at the same time top in dom0 is reporting 1-4% CPU utilization. I see that the TODO for xentop includes a task to make CPU% more accurate but looking at the code for xentop and libxenstat I''m not sure how to go about this. Assuming the CPU

Hi, I''ve noticed that on a Xen cluster with three nodes (two E5620 CPUs and one E5140 CPU) live migration works perfectly in between to two E5620 nodes, but fails to and from the E5140. The error message is about a HVM context not being able to be set. I strongly suspect the use 238 GPPVL drivers, but I cannot uninstall them at this point because someone else needs the server. Could

Hi all, sorry to intrude on xen-devel, but I think I need direction from the expertise here. I''ve admin''d Xen servers of various flavors for a couple years, but never seen this before. After a period ranging from several hours to several days, my primary database and development DomU completely locks up. Net disconnects, but CPU(sec) continues to tick in xentop. No errors, and

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I''m trying to diagnose a reasonably large performance drop between two ostensibly similar servers; one running CentOS 5.5 on bare metal, the other running Fedora 14 as a Xen DomU under CentOS 5.5 (Xen 3.1.2-194.26.1.el5) I have a pair of older Dell PowerEdge 1750 servers, each with 4GB ram and 2x 2.4GHz Xeon CPU''s with

hello all, I''d like to install Fuse on a domU. I''m using debian testing.

Hi All, I have a weird issue I''m not sure how to solve.  I''ve got Xen 3.2.1 working under RHEL 5.2 x86_64 just fine.  I fired off a CentOS 5.2 PV install and everything went smoothly... except that when I fire up the PV, the tap0 for bridging isn''t being created.  This results in the CentOS 5.2 domU''s bridged eth0 only being able to ping the RHEL5

Hi, I''d like to know how to install centos (4.5 in my case) to run as a domU on a dom0 running etch. Any tips please? Thanks. Chris. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hello, is it possible to login into a DomU (Windows) without beeing logged in in the Dom0 on the same PC where Xen runs? So I want to have something like the Windows login screen on e. g. tty2 so I do not need to login twice (first in Dom0 and the second one in the DomU). Thanks for help, Markus _______________________________________________ Xen-users mailing list

Hi all, i have a CentoOS based Xen Dom0 running gitco xen3.3.1. I''m experiencing problems with debian Lenny FV domU. After some days of perfect working the VM start to consume all cpu and than i can only connect via ssh to VM and nothing work, neither the "top" command! Any idea? Thanks a lot and regards, Francesco

I am creating some custom nagios plugins and I am scraping data from xen using the nagios command: /usr/sbin/xentop -b -i 2 -d1 I am trying to get the network tx / rx data, however I think I am missing something here. NETTX(k) NETRX(k) So total network bandwidth is 1048576 k if the above header from xentop is true. So I am wondering why the output for each vm exceeds the theoretical max, Is

Hi, I''m new to Xen and I''ve set up a few domUs using Debian (I suspect there may be a problem there, see at end). To begin with everything worked OK, I rebooted domUs without any problems, but twice now when I try when I try to restart or shutdown a domain, the xm command locks up. # xm list Error: Device 0 not connected Usage: xm list [options] [Domain, ...] List information

Hi all, Wondering if anyone knows of any tools I can run on my Dom0 to log various stats (like CPU usage, memory usage, etc) for each guest domain for analysis over a period of time? I can see that xentop displays that information anyway but would be nice to be able to present that information on a web based interface for day to day administration. Also any tools that send out email

Hi, How can I get network info for domU similar to xm top & then ''N''.. I want to run a shell script to read this.. Thanks in advance, - regards Pallab _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
