[Xen-users] Windows 2008 SBS suddenly disappearing on Xen 4.0.0
Hi all, when running Windows 2008 SBS on Xen 4.0.0, it disappears after some time (longest time I had it running was 20 minutes). In /var/log/xen/qemu-dm-win1.log I find: xc_map_foreign_batch: mmap failed: Cannot allocate memory xc_map_foreign_bulk error 12 Anyone any idea how to troubleshoot this? The Hypervisor has 16 GB of RAM, currently 2 GB are allocated to Dom0. This specific DomU has 8 GB. thx, B. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi all, i was using 2008 SBS without problem on Xen 4.0.1 before migrating to Xenserver 5.6. I agree with James - try to upgrade to 4.0.1 - a lot of hotfixes has been included in that release.

I''m on Opensuse 11.3, upgrading will need to happen outside of the distro packages since 4.0.0 is the highest available. I consider switching back to Opensuse 11.2 which carries 3.4. I had problems installing Windows SBS 2008 on that before though, but since someone confirmed having done that, maybe I should look into troubleshooting that first. thx, B. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

These seem ridiculously slow: 20 MB/sec while writing. This is probably way too slow for Xen and this makes the install reboot while expanding files. Hopefully Dell support can help with that, but Googling for this kind of problem reveils that this is typical for this card which can be deemed as plain old crap. thx, B. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
