Hallo! I am using on a system based on Debian GNU/Linux Etch on AMD64 platform Linux and Solaris running in a HVM domU but they both seem to be 32bit environments. I know so because 64bit Linux didnt boot and said something about am I trying to run it in 32 bit environment; and because i had to install 32bit Oracle because 64bit Oracle said it expected BIT_SIZE=64 and got BIT_SIZE=32. And also, to have under Solaris more than 4GB RAM i needed to add into domU config ''pae=1'' option. Please tell me if there is a way to make HVM 64bit? Best regards, Imre Oolberg PS And also, could somebody explain to me how is this so that in domU witch runs in a full virtualization mode operation system is not seeing real hardware but qemulated hardware. Or is there a way instead of qemu to provide HVM domU real hardware? My hardware is HP 385 DL and domU configuration is kernel = "/usr/lib/xen-3.0.3-1/boot/hvmloader" builder = ''hvm'' device_model = ''/usr/lib/xen-3.0.3-1/bin/qemu-dm'' memory = ''1024'' vcpus = ''1'' name=''domU-hvm-2'' vif = [ ''mac=00:16:3E:3A:9E:7A, type=ioemu, bridge=xenbr2'' ] disk = [ ''file:/data/domains/domU-hvm-2/disk.img,ioemu:hda,w'' ] boot=''c'' vnc=1 pae=1 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

RE: [Xen-users] is it possible to have 64bit HVM domU?
Hello, I think the problem is You use too old Xen version, wich did not support maybe correctly the 64bit processing. I tried 3.0.4-1 and installed successfullly 64bit debian etch and also w2k3 srv enterprise x64. So I would propose to try a newer xen version if You have problems - and first after it still does not work, check the problems with the newer version. As far as I know, during the versions 3.0.x has been fixed a lot of issues in 64bit processing...

Or is there a way instead of qemu > to provide HVM domU real hardware?There is no current way of passing the real hardware to a HVM guest. There is work being done on it, but I don''t know how far it''s got. My earlier post on the same subject had a couple of links in, and a quick Google showed something on the xen-devel mailing list.> > My hardware is HP 385 DL and domU configuration is > > kernel = "/usr/lib/xen-3.0.3-1/boot/hvmloader" > builder = ''hvm'' > device_model = ''/usr/lib/xen-3.0.3-1/bin/qemu-dm'' > memory = ''1024'' > vcpus = ''1'' > name=''domU-hvm-2'' > vif = [ ''mac=00:16:3E:3A:9E:7A, type=ioemu, bridge=xenbr2'' ] > disk = [ ''file:/data/domains/domU-hvm-2/disk.img,ioemu:hda,w'' ] > boot=''c'' > vnc=1 > pae=1 >I''m not sure what the defaults for pae, acpi and apic are in Xen 3.0.3, but it seems likely they are 0. You may have more luck by setting these to 1, it''s worth a try, but as another reply has said, you may have more luck using a newer version of Xen.> > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users-----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGkgI2RnwIDhcMR9MRArlxAJ9YU7SmGy9cc0N+0fdh1kQ431dAwACgrwmb FHnYzwPsdNmYSQvpXQqoZQY=sfAJ -----END PGP SIGNATURE----- _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
