[Xen-users] xen dom0 not reclaiming free'd memory

[John Calderon <jcalderon@xxxxxxxxxxxxxxx>]

Hello:

I have situation with xen 3.2.1 kernel 2.6.26-2 where when I shutdown a VM neither the OS or dom0 sees the free'd memory.

I've searched around and dont see anything related.  Am I missing some config option or something? my /etc/xen/xend-config.sxp is set to
(dom0-min-mem 196)

Regards,

John Calderon

Hi everybody,

I'm very interested in some features promised in xen 3.4.
One of them is the support for PV USB.

So, I've installed/compiled/installed a xen 3.4 (testing) hypervisor and then I've launched a PV domU (using pygrub).
But all my google searches were useless to find any piece of info on how to enable and test this functionnality.

Is this really implemented? If yes, has somebody ever succeeded to use it.

Basically, I'd like to boot my domU then plug a USB stick and mount it on domU.

If I understand well, this should not need any passthrough operation. So I imagine that a specific line must be added on domU's configuration file.


Any help appreciated!

Have a nice day.

Jérémie
