similar to: privileged domU

Hello, I have been using Xen now for several months and have been quite successful until attempting to utilize iscsi within my domU''s. My research has turned up many posts of people using iscsi with no problems, and I have found no others with the problem I seem to be experiencing. If this has been covered on this list in the past, please accept my humble apologies. Configuration:

Thanks for your answers... But IMHO it''s hacky and error-prone to rely on the name of the host to determine if it''s a domU or a dom0 (or an unmodified kernel) :( I don''t like that much neither changing the name of the kernel :-/ I need to be able to determine, as a normal user (that is: non-root), if I''m running in a domU or not (I can already tell if

I am running Xen 3.0.1 with Gentoo for Dom0 and when I create a DomU with Debian, the kernel or system does not seem to recognize the volume I have created for swap on the DomU and will not mount it during boot or after. here is the disk section of the xen config for the DomU: disk = [ ''phy:xen-disks/disk-root,hda1,w'',''phy:xen-disks/disk-swap,hda2,w'' ]

On Unisys 16X 16GB ES7000/one with SLES10 Beta11 updated to xen changeset 9998, attempted to create a 2GB domU and get Error: The privileged domain did not balloon. xm list shows that before the attempt to create the domain, dom0 has 15910 MB memory. After the error, dom0 has dropped down to 13993 MB. Bugzilla number is 650 > Sue Krysan > Linux Systems Group > Unisys Corporation >

I''ve searched in a couple of places, but have yet to find a conclusive answer for this question: is kexec supported for domU kernels, yet? I saw a couple of developer threads about possible implementation, but I tried it in SLES 11 (2.6.32.13-0.5-xen) and I get an error: Invalid memory segment 0x2000 - 0x595fff I was wondering if there''s something that needs to be done for

Hi all, I used netperf to measure throughput between dom0 & domU.

Hi, I have recently started taking a look at Xen and have so far setup a Xen installation on a Fedora Core 5 host. I have also created a FC5 guest which boots up fine. I have found on the internet instructions on how to start the x-server for a linux based guest by using VNC. And, although I''ve managed to start the x-server, it is all done manually. I.e. start the Linux guest, log

Hi all, I used netperf to measure throughput between dom0 & domU. The throughput between dom0 -> domU was 256.00 Mb/sec domU -> dom0 was 401.15 Mb/sec. There is a huge variation in the throughput between dom0 & domU. To my surprise the throughput between domU -> dom0 is more. The value which I specified are consistent values.

Hey, I was looking for step by step installation for RHEL5 as dom0 and RHEL5 as domU, but could not find it.I put some instructions, hope it will save some time for somebody. If you will find some errors please fix them :) I assume that you already have rhel 5 up and running (webserver as well).I will install guest system in paravirtualized mode (mine processor does not support full

Hi, I''m trying to setup xen on a server with bridge networking. I have RedHat as my dom0. I have two Ubuntu instances and one CentOS instance as domU''s. All of them (dom0 and domU) use static ip addresses. The configuration files for domU''s specify in the vif line what ip address to be assigned to that particular domU. It works fine for my ubuntu domU''s. But

I''m running a number of domU''s on a server, each with a console bound to a specific local port. I''d like to provide the users of my domU''s with access to the console, but I was wondering how people have been able to do this while limiting access to the console ports. That is, I could provide the users with a shell on the local machine, but then they could telnet

Hi all, I used netperf to measure throughput between dom0 & domU. The throughput between dom0 -> domU was 256.00 Mb/sec domU -> dom0 was 401.15 Mb/sec. The throughput between dom0 & domU seems to be very asymmetry. To my surprise the throughput between domU -> dom0 is more. The value which I specified are consistent values. Is

I am running Xen on Ubuntu. I am trying to attach a block device(usb pen drive) to domU. When i plug in my pen drive, it gets attached to dom0 on /dev/sdb1. I executed the command xm block-attach 3 phy:/dev/sdb1 /dev/sdc ro (3 is the guest vm''s id) i get the error. Error: Device 2080 (vbd) could not be connected. Device /dev/sdb1 is mounted in the privileged domain, and so cannot be

Hi all Ive just installed an XP and a 2003 server hvm instances. They way I read the docs, a ps2 mouse will automatically map to ps2 in the domU. The problem I having however is that the mouse ''flicks'' off the screen as soon as i activate the window and move the mouse. Just like an incorrect mouse driver was installed. If I look at the windows mouse configuation its using the

Hi, I''m trying to create OpenSolaris (2008.11) domU on RedHat Linux dom0. I''m using a file backed VBD. I used the iso image to first launch and install OpenSolaris into the file VBD. Once that process is complete, I''m trying to run it using the config file below: name = ''opensolaris'' vcpus = 1 memory = "512" vif =

Just something to be added: - This procedure doesn''t work with a Fedora 9 DomU - Maybe you have to blacklist some modules in the Dom0: AFAIK you have to rmmod (better: blacklist on boot using modprobe.conf) these modules: serial_core 8250 and 8250_pnp ----- Ursprüngliche Mail ---- Von: Federico Fanton <fake@panizzolo.it> An: xen-users@lists.xensource.com Gesendet: Freitag, den

Hi, I needed to switch one DomU from one IP to an other tonight. I''m on centos 5.2 (Dom0 and DomU) Therefore, I made a script using perl to make so. This script modify the IPADDR line in the following files : - /etc/sysconfig/network-scripts/ifcfg-eth0 - /etc/sysconfig/networking/devices/ifcfg-eth0 - /etc/sysconfig/networking/profiles/default/ifcfg-eth0 Then I reboot the VM and it

Hi, I use a EQ 4 dedicated root server by hetzner with ubuntu jaunty. I installed xen 3.3 with debian kernel and brought up 3 domUs. Now comes networking... Hetzner does not allow bridged networking so I have to use routed mode in xen. No Problem so far, but the Problem actually is: When I bring up a domU the routing table is created by the xen-script vif-routing. The network interface name
