Greetings, Currently, as I understand PV memory allocation, the Guest''s pfn -> mfn physmap will get populated on-demand as the guest uses more an more of its memory reservation. Is it possible to also make this go in the reverse direction? For example: let''s say we have a guest that is mostly idle and has a great deal of free memory and we decide to balloon down the domain.

Hi, When running domUs with pygrub, I get errors: .... xen be core: xen be core: can''t open gnttab device can''t open gnttab device xen be core: xen be core: can''t open gnttab device can''t open gnttab device xen be core: xen be core: can''t open gnttab device ..... domUs start, but these errors continue on dom0 Configuration: dom0: Ubuntu 8.10

Add a semaphore to protect gnttab_list from exhaustion, and disable callbacks during allocation/free. Fix the network frontend accordingly.

Rather than just leaking pages that can''t be freed at the point where access permission for the backend domain gets revoked, put them on a list and run a timer to (infrequently) retry freeing them. (This can particularly happen when unloading a frontend driver when devices are still present, and the backend still has them in non-closed state or hasn''t finished closing them yet.)

Hi all, These days I installed xen 4.3 unstable from source and recompiled qemu upstream with spice support. After xl create , the windows domU started successfully and spice client can visit the VDI. However, it display blue screen before entering the windows welcome screen. Is it a bug in current upstream qemu support? My domU configuration file is: builder =

I just wonder why xen 4.4 unstable presents it self as xen 4.3 unstable ? boot message states 4.3 unstable and efi is 4.3 unstable? I wonder what is the reason behind it ? _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

This patch implements the xenidc_channel interface using grant tables but leaves the channel bring-up and tear-down sequencing to a derived class (xenidc_gnttab_channel implements that). This code is part of the implementation of the xenidc_endpoint used for interdomain communication by the USB driver. Signed-off-by: Harry Butterworth <butterwo@uk.ibm.com>
