Log files? There can be a pertinent log file only if you have some daemon running transferring the hypervisor log into a log file. Otherwise you need to look at "xl dmesg" output. > This was the test of Anthony Perard with all details about the problem: > http://lists.xen.org/archives/html/xen-devel/2013-05/msg02050.html See the "bad mmio size 16" and "MMIO emulation failed @ ..." messages there? > So my questions are: > - Is your patch aimed to completely solve cpus instrictions with MMIO > operands > 8 byte or > - does it need also some qemu changes? The patch is aiming at completely solving the in-hypervisor emulation issues with operands of more than 8 bytes in size. Whether on top of that a qemu change is also necessary I don't know, but I wouldn't have expected so.
