Re: [Xen-users] How to set up 'vmxassist=n' when doing Xen 3.2 build on CentOS 5.1 ?

[Boris Derzhavets <bderzhavets@xxxxxxxxx>]

There is very easy way to find out vmxassist status :-
Try HVM Solaris 10 (05/08) DomU install
1. if it hangs vmxassist has not been disabled
2. if it goes  vmxassist has been disabled.
Same way works test Free BSD 7 (i386).

All:

Is there any way to tell if vmxassist has been disabled by examining the
binaries?

bash-3.2# strings /usr/pkg/libexec/qemu-dm|grep -i vmx
(HVMXen) 
HVMXEN-

bash-3.2# gzcat /xen.gz |strings  |grep -i vmx
vmx_intr_assist
vmx_vmexit_handler
vmx_do_invlpg
vmx_set_cr0
vmx_world_restore
vmx_io_instruction
vmx_do_msr_read
vmx_do_msr_write
vmx_restore_guest_msrs
vmx_vmcs_restore
