Attach CDROM to windows
Hi Guys,
Now I am using Xen-4.0.0. I need to attach CDROM from ISO files to vitual
machines when they are running. The VMs contain RHEL4.6, Windows Server 2003
32bit and Windows Server 2006 64bit.
The disk configuration of the VMs is:
disk = [ ''tap:vhd:/guest/SS_test/vhd/hmi-100130.vhd,hda,w''] (1)
When I attach a CDROM to RHEL4.6 VM with the command:

HVM creation problem
Hi,
I''m kinda new to XEN stuff, and I''ve been trying to create a fully virtualized guest on CentOS 5.3 for almost 3 months and no luck yet. I approached this process through several methods, one with virt-install and creating config file manually.
Following is what happens when I try to create a guest, and I have included qemu-dm and last part of xend.log logs below too.

Error: Device 2049 (vbd) could not be connected. Hotplug scripts not working
Hi,
have a debian 5.0 with all patches and xen 4.3.1 (debian repo)
installed. If I use a VM with paravirtualizing it works fine.
But a full virtualized image doesn''t boot.
Message:

BUG 4.2.2: xl cd-insert corrupts xenstore state
$ git checkout RELEASE-4.2.2
$ git clean -ffdx
[do a build, install, reboot]
$ xl create a0
$ xl cd-eject a0 hdc
[However, the guest OS still sees the CD inserted]
$ xl block-list a0
Segmentation fault
$ xl cd-insert a0 hdc file:/images/xs-tools-6.0.0.iso
Segmentation fault
The problem seems to be that xl cd-eject is writing corrupt values to
xenstore. Note that vbd/1/5632 is still there

Re: xm create: Error: Device 0 (vif) could not be connected. Hotplug scripts not working. One more question.
Next question:-
eth0 8000.001c2596e32b no peth0
pan0 8000.000000000000 no
virbr0 8000.000000000000 yes
Presence virbr0 in report seems strange. Direct port Xen 3.4.2 to F11 doesn''t install daemon
libvirtd ( bridge virbr0 ) , unless you wrote xen-3.4.2-(x).fc12.src.rpm yourself.
So , from where bridge virbr0 comes

Live migration fails depending on on the kernel Version of DomU
Hi,
I''m running a two node xen-Cluster with CentOS 5.3. I''m using
gfs2 for the cluster filesystem and kernel 2.6.18-128.1.6.el5xen #1 SMP
for Dom0 (xen 3.0.3).
Live migration works fine as long as the DomU guest is running CentOS 5.3
or SLC 4.7 with kernel version 2.6.9-55.EL.cern. But if the SLC 4.7
guest is
running the current 2.6.9-78.0.17.EL.cern kernel, the migration

Centos 5.2 using LVM -> DRBD 0.82 -> Xen Problems
Hi Everyone,
I''m trying to get Xen to use a native DRBD device but it seems it will
not create the virtual machine. It does not seem to like the DRBD device
type, any ideas on what might be wrong?
I''m pretty sure my xen config file is OK and the DRBD device looks fine
too.
Full details below.

Problems installing windows 2003 std and x64 as guest
I am running Pentium D 930 with 2 gigs of ram.
Fedora Core 6 with Xen enabled.
I am able to start the install and it goes to the first stage of needing to
be rebooted. I restart the Domain and it starts to finalize the windows
install. And is fine until it starts asking for serial numbers or computer
names. Then all of a sudden the guest freezes. The guest CPU goes to zero
