Can you please check the vcpu status? I suspect one of the vcpu is blocked by halt instruction.

Hi, Keir: the gdtr information in oldctx is an address for guest, not for vmxassist. When access descriptor on guest gdt, we need to go through guest page table if guest enable paging. This error may happen if guest enable PE/PG in one instruction. This patch fix this issue. Signed-off-by: Yunhong Jiang <yunhong.jiang@intel.com> Signed-off-by: Xin Li <xin.b.li@intel.com> Thanks

Not yet, but I don''t see any reason for it to work any differently.

The lmsw instruction can be used to set CR0_PE, but can never clear it, once set. Currently, as far as I can see, there is no provision to keep lmsw from clearing CR0_PE, either in the vmx code or in x86_emulate code (which is used by SVM to emulate lmsw). This patch fixes this issue. Signed-off-by: Trolle Selander <trolle.selander@eu.citrix.com>

If anyone is still interested in this old thread, I have a rh7.3 image running under hvm. It''s a hack, but here''s what I did: Install rh7.3 in a vmware machine with vmware server.

Illustration of how VMI inlines are used to greatly limit the impact of code change in low level assembler code. Spinlocks, system calls, and the fault handling paths are affected by adding some padding bytes to convert the native instructions into a hook point for the hypervisor to insert shim code. These changes are sufficient to glue the Linux low level entry points to hypervisor event

Hello! I want to run windows in xen. My linux distrution in ubuntu 6.06 amd 64. I downloaded and installed xen 3.0.2 from binaries.
