Description Justin 2008-12-23 02:02:52 UTC
svm processor ability missing from /proc/cpuinfo after booting into xen kernel 2.6.18.  svm shows properly for livecd kernel 2.6.24.  these are opteron 2210 processors.  (hvm USE flag only applicable for xen-tools; this is RE xen kernel) appears to cause crash on hvm guests but still testing ...

Reproducible: Always

Steps to Reproduce:
1. emerge xen
2. build domO kernel (per gentoo handbook- selecting Opteron processor, Xen Hypervisor, etc.)
3. reboot

Actual Results:  
cat /proc/cpufino | grep svm 

Expected Results:  
svm

Please paste your emerge --info output. Also, can you try a newer xen-sources version? Also, paste your emerge -pv xen-sources output, your "uname -a" and any other debugging information. You say about 2.6.18 kernel, but which xen-sources version exactly? Also, attach your kernel config in case you don't solve the issue on your own. I will leave the bug ASSIGNED (which means accepted) until you have submitted more information.
