[Fedora-xen] Xeon Core 5130 couldn''t support full-virtualization?
Hi, lists, Now I dive the sea of xen, I took a Dell 2950 Server, install FC 6 i386 on it, I refer some documents about Xen: http://www.fedoraproject.org/wiki/FedoraXenQuickstartFC6 So i checked as following: 1. check Intel VM for host CPU, it works, it showed me: flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc pni monitor ds_cpl vmx tm2 cx16 xtpr lahf_lm 2. check hvm-??, then I have no luck. even I enable virtualization in BIOS. so how could I enable fully-virtualizied in this server? or should I install x86_64 for it? Because this server CPU is Intel Xeon Core 5130 serial. Thanks a lot, Zhou Zhen

Running xm dmesg | grep VMX should confirm that Xen has picked up the support from the hardware. (Note some platforms have a flag to disabled this in the bios).> > > 2. check hvm-??, then I have no luck. even I enable virtualization in BIOS. > > > > so how could I enable fully-virtualizied in this server? or should I > > install x86_64 for it? > > If you are running 32-bit you should use the PAE kernel to be able to > use the VMX feature (AFAIK).All the FC6 xen (and RHEL5) kernels are PAE enabled. You should be running the xen kernel. As for 64bit or 32bit that''s a longer discussion. One factor in your decision is how much memory you have. x86_64 handles large memory installations.> > > Because this server CPU is Intel Xeon Core 5130 serial. > > > > Thanks a lot, > > > > Zhou Zhen > > Cheers, > Jurgen> > -- > Fedora-xen mailing list > Fedora-xen@redhat.com > https://www.redhat.com/mailman/listinfo/fedora-xen-- Andrew Cathrow Red Hat, Inc.
