Hi, I recently started working on XEN, and I am looking for ways to invoke hypercalls from HVM. I followed your instructions and succeeded in reading MSR register. But when i attempt to write the physical address of a 4K page from my HVM guest (2.6.30 kernel), i observed the XEN hypervisor reporting it as bad GMFN as follows. [root@f13 ~]# xm dmesg -c (XEN) traps.c:664:d17 Bad GMFN ffff88001e925 (MFN ffffffffffffffff) to MSR 40000000 Could you please help me in understanding what went wrong in my implementation. I am running XEN 4.0.1 on AMD 64bit machine with svm support and the dom0 kernel running 2.6.32.39. The Thanks & Regards, VSR. -- View this message in context: http://xen.1045712.n5.nabble.com/HVM-hypercalls-tp2541346p4418332.html Sent from the Xen - Dev mailing list archive at Nabble.com. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
