Hello, Is it possible to run a Xen server inside of a kqemu/kvm/virtualbox VM? I am new to Xen, and Linux in general. (Just installed Ubuntu 7.10 on my main laptop) The idea would be to try and learn about Xen before attempting to deploy on real HW. -- Thanks P.S. I do have an Intel VT capable CPU, if that matters. --------------------------------- Never miss a thing.

Do you know if any of the other above mentioned solutions will work? I''d rather not install VMware server on my main work machine... to much potential for day-to-day issues. Ideally, I''d like to also stay on the Free side of the fence, if possible. Is there a HOW-TO somewhere? Thanks, David --------------------------------- Be a better sports nut!

Virtualbox is free to use for individual/evaluation purposes. Virtualbox OSE is GPL, opensuse 10.3 even include it as part of the distro (not installed by default). qemu should work, but probably much slower compared to other alternatives.

[Xen-devel] how to make checkpoint for a PV vm , while maintain it running ?
hi I have tried to make checkpoint for a PV vm with"xm save -c dom1 /tmp/dom1 "in xen-3.1.0,the ckeckpoint file could be used to restore the vm, but the vm do not continue to run ,after "xm save -c dom1 /tmp/dom1",the vm could not be accessed through console ,could not be shutdown using"xm shutdown dom1" and could not be pinged from dom0, but "xm destroy dom1" could work, should some configures be set before "xm save -c ",or what should i do to make a vm checkpoint, while maintain the checkpointed vm running? Thanks in advance _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

So I''d suggest first upgrading Xen, and then if you still have problems, build xen with debug=y verbose=y and see if anything turns up in xend.log or /var/log/daemon or the guest console. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Re: [Xen-devel] how to make checkpoint for a PV vm , while maintain it running ?
hi Thank your for your advise that is to say , xen-3.1.0 does not support checkpoint while maintaining PV vm running ,is it ?or maybe ,there are something I have missed beforing checkpointing on xen-3.1.0, for the node is shared by some fellows at present, i guess I will try xen-3.1.1 later, but how to deal with it on xen-3.1.0 anyway ? or it could not on xen-3.1.0?

(knowing the reason helps understand the > answer.)Actually you can run a Xen with PV guests inside an HVM virtual machine hosted by Xen. I generally run a known-good Xen on my test machine and then run development versions of Xen inside HVM virtual machines. You *can''t* run Xen in a PV domain for the reason Tom stated, so if you don''t have HVM-capable hardware this won''t work. It''s not possible to run HVM-capable Xen *inside* an HVM virtual machine because Xen can''t currently support nesting HVM. Cheers, Mark -- Dave: Just a question. What use is a unicyle with no seat?
