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 identity page table and enter protected page mode. In this step I also...

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.

hvm: clear vmxe if vmxoff The current Xen code keeps X86_CR4_VMXE set even if VMXON has not been executed. The stop_vmx() code assumes that it is possible to call VMXOFF if X86_CR4_VMXE is set which is not always true. Calling VMXOFF without VMXON results in an illegal opcode trap, and to avoid this condition this patch makes sure that X86_CR4_VMXE is only set when VMXON has be...

...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 already running? is there a way to check if one is running?? 2. before i set the vmxe bit in cr4, i check if it is already enabled. i do this while my module gets loaded. but i observed a strange thing. sometim...

Dear mailing list I just installed Suse 10.1 with Xen support on a computer with an dualcore Intel processor. Is ther any documantation around on how to configure the xen, that it supports the intels vt technologiy.

...t 6 (Installation hangs at "Setup is starting Windows"). I am running Fedora Core 5 with Xen 3.0.2 and the related kernels installed, and using the solution described here does not work for me. I have an Intel P4D 930 CPU on an Asus motherboard, and xm dmesg | grep VXMON shows (XEN) VMXON is done (XEN) VMXON is done This seems correct as I have a dual core Intel CPU. Can anyone advise anything else I could try to get Windows XP to work in this configuration? I''m currently building Xen-unstable, but I''m hoping for a more straightforward solution than having t...

Am considering a new laptop, and I wonder if anyone here can share their Xen experiences with the newest Core 2 Duo CPUs, ref http://www.intel.com/products/processor/core2duo/specifications.htm The list at http://wiki.xensource.com/xenwiki/HVM_Compatible_Processors doesn''t include any Core 2 Duos. Does that mean that people have had problems, or is the wiki just not up to date? I gather

I am trying to get QNX working with Xen. I''ve going about it in a similar way as installing windows with Xen, but when I start the guest up to install the OS it hangs on the line: ''Hit Esc for .altboot.......'' If anyone has managed to get this working, or has any ideas/advice for me here it would be greatly appreciated! Bryan

Hello group, I recently purchased an HP m7360n computer which has an Intel Pentium D 920 processor in it. Unfortunately there is no BIOS option to enable or disable VT. The board it sits on uses the Intel 945P chipset. If I am in linux and do a ''cat /proc/cpuinfo'' I get this: [root@localhost ia32]# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family

However, I wonder that it does not show anything when commands show VT-x availability such as ''xm dmesg | grep VMX(or VMXON)'' and ''grep vmx /proc/cpuinfo'''' are entered. these commands usually works but not with this server model: Dell 2950 cpu: Intel(R) Xeon(R) CPU L5335 @ 2.00GHz xen version : 3.4.1 I would like to thank you in advance for your help :) __________________________...

I''m using FC5 with its Xen 3.0.2-2 package and 2.6.16-1.2118_FC5xen0 kernel.
