Re: [Xen-users] Bootable LiveDVD w/ Xen that boots Windows Image?

Hi Joshua,

 Take a look at this web pages, maybe that can help you:

http://wiki.xensource.com/xenwiki/COWHowTo

http://lxr.xensource.com/lxr/source/tools/blktap

 I'm sorry but I never have used the qcow with Xen... If you need any help to get you Windows domU running within the Xen Live CD, will be a pleasure try to help you.

Cheers!

Hey Thiago,

 

I actually had come across that and was looking at it.  I think it might do most or part of what I'm looking to setup (the Linux LiveCD part), as I'm using Debian Leny for the Linux side.

 

I'll have to check out this qcow2 file image setup some more.  Fajar mentioned in a mail after this one that feature may still have problems.  Are there any documents someplace detailing the qcow2 setup?

 

Speed isn't really going to be a factor for me, even though it'll likely be dog-slow anyways (CD-ROM read speed + squashfs decompression + Windows' sasquatch-sized footprint + specialized application we need to run).  But if it works, that'll be awesome.  At least I'll get a coffee break while the whole mess would boot up....

 

Thanks!,

Hi Joshua!

 The new Xen Live CD v2.0 does this, but with a Ubuntu domU instead of Windows domU...

 Take a look at the Xen Live CD wiki page, so you can learn how to buid your own Xen Live CD with your Windows Guest installed...

 Xen Live CD: http://wiki.xensource.com/xenwiki/LiveCD

 The domU guests has a read-write root file system powered by SquashFS, so you must use something like qcow2 file image, I don't know... I hope that the Xen Live CD can help you!

Cheers!

Hey all,

 

Need to know if ths sounds like a crazy idea or not.  Not really messed with Xen a whole lot, but I have played around with other virtualization technologies, so I'm not 100% if I can do what I'm after.

 

Basic gist is, I want to create a small Xen dom0 install, primarily using Debian Lenny 5.0.2, and from it, boot a Windows XP domU instance, but do all of this from a single bootable DVD disc. I think I've got the basics down behind setting up a bootable Linux DVD, as I've built netboots before and found some some scripts which might help.

 

The tricky part is going to be the Windows install.  I figure I can install it on a read-write virtual disk, and later package that image up for booting off of the DVD.  The only curiosity is going to be how well Windows takes it, because it scibbles all over the place (Registry mostly) when it boots.  There's a specific application I need to be available when this whole mess boots up.  I won't use said app very often (1-2 times/month), but I don't want to keep an entire Windows install around for it.  I'm thinking it'd be easier to somehow get this onto a bootable medium, and since Windows wasn't designed to boot off of CD and DVD media, I figured that this would be the next best idea.

 

Or if people have better ideas, I am all ears...

 

Thanks!,
