Hi, everyone! We google a lot, but can''t find how to config the pvscsi on our ubuntu13.04 PV on HVM.There are some links http://wiki.xen.org/wiki/Paravirtualized_SCSI http://wiki.xen.org/wiki/Xen_Configuration_File_Options And we use the config option above Configure PVSCSI devices vscsi = [ ''/dev/sdc, 0:0:0:0'' ] I pass sdc to the hvm, but in our pvhvm (ubuntu13.04)

Hi all! I want to assign a physical network card (e100) to a domU: I think Dom0 is ok but domU does not recognize the pci nic. into DomU I don''t know wath should I see: I have nothing in dmesg nor in messages... Into Dom0 I have this modules.conf: options pciback hide=(0000:03: 08.0) install e100 /sbin/modprobe pciback; /sbin/modprobe --ignore-install e100 This is dmesg: pciback

Hi Everyone, In Xen, is a DomU able to access data in RAM which a previous DomU has stored in the past, but didn''t "zero" it? I understand that this is a problem with physical disks (using phy:/), just wondering if the same stands with RAM Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com
