Hi everyone,<br><br>I need to use full virtualization on my laptop, running CentOS 5.2 as host. I installed all I think is needed to run Xen. I am using kernel 2.6.18-128el5.xen as it is needed to recognize my wifi card.<br>
I was not sure my cpu supported Intel VT. A cat /proc/cpuinfo | grep flags yields this:<br><br>flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall nx lm constant_tsc pni monitor ds_cpl vmx smx est tm2 cx16 xtpr lahf_lm<br>
<br>I guess vmx means VT is supported even if, for my T9600 cpu, it is not officially stated on Intel website (it is up to T9400).<br><br>VT is enabled in the BIos.<br><br>When I try to add a virtual machine with virt-manager choosing Xen as hypervisor, the "enable kernel/hardware acceleration" checkbox is grayed out. How can I solve this?<br>
Moreover, if I run CentOS on a non-Xen kernel (i.e.: 2.6.18-128el5) I cannot use xen of course, but if I choose Qemu as hypervisor in virt-manager, the checkbox is available. How can it be?<br><br>Thank you very much for your help,<br>
