When you attempt to create a guest, you receive an "Invalid argument" error message. This usually means that the kernel image you are trying to boot is incompatible with the hypervisor. An example of this would be if you were attempting to run a non-PAE FC5 kernel on a PAE only FC6 hypervisor.

当​​​​​​​你​​​​​​​用​​​​​​​ yum update 来​​​​​​​更​​​​​​​新​​​​​​​内​​​​​​​核​​​​​​​时​​​​​​​，grub.conf 里​​​​​​​的​​​​​​​缺​​​​​​​省​​​​​​​内​​​​​​​核​​​​​​​选​​​​​​​项​​​​​​​切​​​​​​​换​​​​​​​回​​​​​​​普​​​​​​​通​​​​​​​内​​​​​​​核​​​​​​​而​​​​​​​不​​​​​​​是​​​​​​​虚​​​​​​​拟​​​​​​​化​​​​​​​内​​​​​​​核​​​​​​​。​​​​​​​

要​​​​​​​解​​​​​​​决​​​​​​​这​​​​​​​个​​​​​​​问​​​​​​​题​​​​​​​，你​​​​​​​必​​​​​​​须​​​​​​​修​​​​​​​改​​​​​​​ /etc/sysconfig/kernel/ 目​​​​​​​录​​​​​​​里​​​​​​​的​​​​​​​缺​​​​​​​省​​​​​​​内​​​​​​​核​​​​​​​ RPM。​​​​​​​你​​​​​​​必​​​​​​​须​​​​​​​确​​​​​​​保​​​​​​​在​​​​​​​ gb.conf 文​​​​​​​件​​​​​​​里​​​​​​​ kernel-xen 参​​​​​​​数​​​​​​​被​​​​​​​设​​​​​​​置​​​​​​​为​​​​​​​缺​​​​​​​省​​​​​​​选​​​​​​​项​​​​​​​。​​​​​​​
