similar to: [PATCH] hvm: clear vmxe if vmxoff

Hello, I tried to write a piece of code to start vmx. This code is directly interacting with cpu instead of with virtual cpu as in xen. But every time I call vmxon, a GP exception happens. Could anybody help me on this? The following is the context 1. After booting up to the program, I disable A20M. 2. allocate a 4kb-aligned vmxon region and calculate its physical address. 3. setup

Hi guys, let me shortly introduce myself. I''m a student and recently work on my bachelor thesis. My goal is to write a little hypervisor. I''m not quite sure if this is the right mailing list, but i guess you''ll gonna tell me. i have two quick questions: 1. before i can use the vmxon instruction i do have to set vmxe flag in cr4 register. but what if some hypervisor is

Hi all, A while ago there was a thread here titled "Xen w/ IntelVT->Windows Success Report" http://lists.xensource.com/archives/html/xen-users/2006-06/msg00452.html I am having a similar problem as this user was in point 6 (Installation hangs at "Setup is starting Windows").

Not sure if this is a Fedora Core 6 issue. I already post a message on their list but didn''t get an answer. So I am going to try here..

If I don''t lower the memory assign to Dom0 through grub, I will not be able to run a Windows Guest OS. This what I got Using

X86: implement PCID/INVPCID for hvm This patch handle PCID/INVPCID for hvm: For hap hvm, we enable PCID/INVPCID, since no need to intercept INVPCID, and we just set INVPCID non-root behavior as running natively; For shadow hvm, we disable PCID/INVPCID, otherwise we need to emulate INVPCID at vmm by setting INVPCID non-root behavior as vmexit.

VT is enabled in BIOS and ''xm info'' shows that hvm can be created like below: xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm -3.0-x86_64 Several Windows VMs have been created on this server and running perfectly. However, I wonder that it does not show anything when commands show VT-x availability such as ''xm dmesg | grep VMX(or

hvm_enable() copies the table contents rather than storing the pointer, so there''s no need to keep these tables post-boot. Also constify the return values of the per-vendor initialization functions, making clear that once the per-vendor initialization is complete, the vendor specific tables won''t get modified anymore. Finally, in hvm_enable(), use the returned pointer for all

From: Yang Zhang <yang.z.zhang@Intel.com> We exposed the xsave feature to guest, but we didn''t allow guest to set CR4.OSXSAVE when guest running in nested mode. This will cause win 7 guest fail to use XP mode. In this patch, we allow guest to set CR4.OSXSAVE in nested mode when it has the xsave feature. Signed-off-by: Yang Zhang <yang.z.zhang@Intel.com> ---

Hi, I have a Dell opt 755 machine and installed Xen 3.3.1. The CPU is core 2 due E6550, which as the vmx flag. However, when I reboot the machine to xen 3.3.1. I can not find vmx in the /proc/cpuinfo. But vms appears in the kernel 2.6.29 (not xen kernel). Can anyone help on how to enable vt in this machine? Thanks.

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

I''m using FC5 with its Xen 3.0.2-2 package and 2.6.16-1.2118_FC5xen0 kernel. I''ve got a Pentium 9xx chip with virtualization enabled in the BIOS; it appears to be VT-enabled, since xm dmesg includes "(XEN) VMXON is done". I base my config file on example.hvm and on previous emails to this list. Unfortunately, I don''t get very far. xm create winxp.conf

Does that mean that people have had problems, or is the wiki just not up to date? I gather
