real HDD usage of XEN images
Hello, i am creating my XEN VM with virt-install (see below). When I create new images i do first an "df -h" to see if there is still enough space left on the drive. Are the XEN images pre allocated or does XEN only use that space that really is used by the VM inside the image? I know have the Problem that an "du -h" inside my /VM folder gives me nearly a higher number that

No shared physical device in virt-manager
I am fairly new to xen and am trying to build a new guest using virt-manager. When I get to the screen where you can choose virtual or shared physical device there are no physical devices to choose from. Is there some step that I have missed while setting up my Dom0? -Joel Coopersmith Sr. Systems and Networking Analyst joel.coopersmith@accenture.com

DHCP and DomUs: not working
I''m trying to get DHCP working with DomU clients. I don''t want to use libvirtd. There''s a dhcpd on the machine and it works fine for all clients in the network, but not for DomUs. If I set a static IP on the DomU all networking for them is fine, so there''s no general networking problem. I use the xen 3.2 packages for CentOS on CentOS 5.1. There was a public

network-bridge breaks networking when eth0:1 is added
I added a virtual interface eth0:1 on one of my machines and suddenly networking breaks on startup of the system (eth0 is gone) when xend starts and runs the network-bridge script. This is supposed to be fixed according to: https://bugzilla.redhat.com/show_bug.cgi I checked and the network-bridge script contains this fix. It works fine on one of my PCs when eth0:1 is added, but not on this

Creating a Bootable Image file
Newbie Question: We are using RHEL 5.2 with the 2.6.18-92.1.6.el5xen kernel. I am trying to follow instructions that I found to create an bootable image by doing the following: I first created a 10 gig file and formatted the partition using the dd and mkfs.ext3 commands: dd if=/dev/zero if=generic.img bs=1024k count=10000 mkfs.ext3 -t ext3 generic.img >From a working image that I

Partition vs disk images
I realize this might be one of those religious topics, but is there any good rule of thumb as to how to setup storage for a Xen domU? Without really knowing any better, I''m basically going to make a disk image of the OS and the create a ''data'' partition on my raid 5 volume for each virtual machine. This is for use at home, so in reality it probably doesn''t

migrate file-based vm to lvm?
I recently upgraded storage on our (first) xen server and would like to migrate the file-based vms I have in play to lvm-based storage... Can anyone point me in the right direction? Is there a way to mount a vm image file like I would using a iso image and a loopback device? Each vm''s disk file contains a partition table with root and swap partitions... In retrospect I wish I''d

Swap memory: I can't reconcile this stuff.
I need to look more into it, but before I start the long and arduous "googling my life away" process, I figured someone might know the answer. I've read the man pages several times and they didn't change! :-( As normal, while looking at one thing, something else bites my butt. I tuned on the swap field in top and sort on it. Here's an edited snippet of the results. Mem:

Disable memory balloon in dom0
Is there any reason why I would not want to set dom0-min-mem to 0 or to what I set dom0_mem on my kernel line? Setting to 0 or setting to the same value as dom0_mem disables memory balloon correct? I cant seem to think of a reason why I would want memory ballooning. Also setting dom0-min-mem should that be done in xend-config.sxp or on the kernel command line? -- Nick Anderson

Quation about CentOS 4 xenU kernel
I converted a physical maschine running CentOS 4.6 to a Xen VM on a CentOS 5 host. Almost everything was running when I decided to rsync /lib and /usr a while later in order to get updated files and get the one or two non-working programs to work. There are differences because of the xenU kernel I didn't think about. I forgot to exclude rpm database and /lib/modules. Because the synced

Web tool for management xen DomainUs ?
Hi! I like to allow to several DomainUs admins to admin his virtual servers with a web interface, without contact with Domain0. This tool must be opensource, and allow shutdown, reboot and see the logs with a web user / pw. Perhaps too the memory, CPU, ,,, of the virtual server. Are there any tool some this? Any pointer will be welcomed. Regards, Agustin

Winamp 0% Buffering mp3 streams
I'm new to streaming or music hearing over the wire, I still prefer my old-fashioned stereo equipment :-) But a friend asked me to setup a shoutcast server for him, so I went out and installed it, played a bit with it and didn't like it. So I looked for an open source alternative and found Icecast. Installed fine, works fine. But there is one thing which puzzles me and I hope someone

DHCP for Xen VMs
I created my first Xen VM that didn't use a static IP address. It grabs an IP from the 198.168.122.0 subnet (from I don't know where). I would rather want it to use my DHCP server. How can I achieve this? Kai -- Kai Sch?tzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com
