Hi. I need more space on my domU server, so i create a file image to attach it to the domU. But when i load that image in the domU, show a size very different to the create. I create the file with this command dd if=/dev/zero of=/xen/domains/SRV03/opt-disk.img bs=1024k seek=30720 count=30720 (The idea is create an image disk with 30GB, but when i check the disk on the domU show 64GB.)

Hi, I am a Xen newbie and have been trying to get Xen-3.4.1 working on my Ubuntu Lucid (kernel version 2.6.32-21) system, using kernel 2.6.18.8 as dom0. In attempting this, I ran into the following issue. On booting into Xen, I get these errors: Mounting none on /dev failed. No such device. ... Gave up waiting for root device. ... Alert! Could not mount /dev/sda1 as root device. Dropping to a

Hi, I created an HVM type virtual machine and installed RHEL5U7 guest in it. I have assigned 7 scsi disks to the virtual machine in physical mode (using phy:), however, I see those disks are xvd and not as scsi. Is anyone aware what the problem might be ? Please let me know what kind of information do I need to post in order to narrow down to the problem. Thanks, K

Hello, I am still confused: does pyGrub run in dom0 as root? as it says in here: "PyGRUB used to act as a “PV bootloader”: it runs in dom0 as root, opens the PV disk image, reads its GRUB menu.lst, presents a GRUB-like menu to let the user choose a kernel which it copies to the dom0 filesystem, it then closes the disk image and eventually tells the domain builder to use that copy. Such a

I would like to understand what may be needed/useful for the system NIC. My plan is to use an Asus mb, Sabertooth or Crosshair.  They both have a single on-board Ethernet port.  I am wondering about the possibility/need to have a 2-port plug-in NIC.  A scenario is to have a domU Windows or Linux SVN/Apache/PostgreSQL VM and interact with it through another domU Windows or Linus VM.  I also may

Hi, What is the preferred OS to use with XEN, as the dom0 host? We primarely us CentOS (currently 5.6) but it seems that the native XEN that comes with CentOS is a bit behind.

When I try to virt-install a PV instance of F11, I''m getting an ''invalid kernel'' message, as if it''s not a Xen kernel. I have tried both the i386 and x86_64 versions. Is there any weirdness with this distro that I''m not aware of?

Hey all, I''m trying to figure out how to re-size physical partitions in the Dom U. I''ve read up what I can find on line and finally decided to have Logical Volumes in the Dom 0 and pass them as physical volumes for use in the Dom U. Here''s an example of what I''m doing. To start in the Dom 0 I created the LV''s with lvcreate -n guest_boot -L 100M

It''s a bit OT for this list, but I''m sure people here will have dealt with it. Does anyone have any suggestions for simple methods of staging machine (Linux in my case) startups when there are interdependencies ? Eg, most of my servers rely on the DNS, so it would be nice if they could wait till the DNS is running before starting - otherwise I end up having to log in and

With code I have found used in multiple places I can easily get 2 bridges, and
