Jean Guyader wrote: Hi, This patch add the pv guest support for the cpuid configuration and checking. That feature only works for cpuid request which are coming from the guest's kernel, a process could still call the cpuid directly. A new policy for pv guest has been created in libxc. dom0 cpuid emulation is left hardcoded in Xen. So at the moment my pv guests are getting all zero back from cpuid. I haven't updated their config files at all. Is that the expected behaviour? It seems a bit unfriendly; I would have expected it to default to the old behaviour with no config in place. Hm, or maybe something else is going wrong? Thanks, J _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
