how to create /dev/xvda
Hi All,
The following is my domU''s cfg file.

ramdisk = ''/usr/local/src/xen/initrd.img''
memory = ''256''
name = ''centos5.2''
vif0 = [ ''bridge=xenbr1'' ]
disk = [ ''phy:/dev/server/cbox,xvda,w'' ]

Is XVD live resize possible?
Hi!
Say I export an LVM logical volume from dom0 as /dev/xvda to the domU:
disk = [ ''phy:xenimages/stan,xvda,w'' ]
No I can lvresize xenimages/stan in dom0, but the domU stays ignorant
of this change. How could I propagate the resize to the domU without
rebooting or temporarily breaking its connection to /dev/xvda? Sort
of a SCSI rescan, perhaps?

LVM + kickstart -> dom0 && domUs
centos-virt,
I'm trying to create/install domU guests all in "one" step, following
Daniel's wiki page (I've found these pages really helpful, BTW):

I have a few questions about this process:
(1) How would it be modified (w/respect to defining the disk in the
domain configuration file) to use a disk layout where dom0

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

Questions on qcow, qcow2 versus LVM
I''ve been using lvm under centos to create the backing store for domUs and
although the performance seems acceptable it has some shortcomings. The
biggest of which is the LVM bug which prevents me from removing an lv (it
says it is still mounted and it definitely isnt). I thought this was just
a centos bug but it appears to be evident in debian and ubuntu too and I
really can''t

Installing openSuSE 10.3 as PV-guest on a LVM-drive of a openSuSE 10.3 host
Hi,
how can I install a openSuSE 10.3 PV-guest on a LVM-drive of a openSuSE
10.3 host with Xen 3.10?
On 10.2 with Xen 3.0.3 the openSuSE-YaST-module for managing VMs could
install the system also on block-devices, unfortunately this is not
possible anymore with OSS 10.3 :-(
What I have tried:
- I created two LVM-partitions, one for "/" one for swap.
- Installing an OSS 10.2 PV-guest

Writing a tool for Shared Persistent Windows Boot Image
Before, in my "Hard Problem" email I was trying to communicate a
design issue were trying to solve with Xen.
This is what we need to do:
1) Deploy 24 Windows XP VMs in parallel.
2) Boot them from a shared Windows XP C: drive.
3) Since this is a read-only shared image we obviously can''t have
multiple VM''s writing to it.
4) All writes to the boot image for logging,

RFH: loopback & blktap(2) and CDROM
Hello,
I''m currently trying to understand some problems I had in the past with mixing
look-back with blktap(2) for HV and PV domains. I''m stuck reading the source
code, so I''d like to get some help from the list. Interrupt me if I got
something fundamentally wrong in my understanding so far:

Initially I did a test with image files and everything went fine, I booted

Re: Using diskOnKey as additional disk - is it possible with default configuration?
Mats,
Thanks for your trial; following your mail I tried it with hda; it
is the same, it does not work -
"fdisk -l" does not show hda.

CentOS 4 and CentOS 5 DomU on CentOS 5 Dom0: problems with hand-built OS and LVM
I''ve been running any number of CentOS 4 based Xen hosts and guests

I like the jailtime approach:

LVM related bug in the GPL PV drivers for Windows?
Dear Xen users!
In case you were struggling with recent version of th gplpv drivers,
I''ve possibly found an LVM related bug in it, and reported to James
Harper. Thats''s the point:
I''ve tested the mentioned version of your driver on top of 32bit
xen-3.2.1 32bit xen-3.3.0 and 64bit xen xen-3.3.0 hypervisors, dom0 was
always an appropriate version of a 32bit PAE kernel,
