I just saw this :} - thanks for the tip. I will thank Geert later on :}
Will let everyone know when I post the blueprint… Thanks Kyle There’s 2 small issues that you need to work around: Due to an issue with the the user-mode CPU detection in libvirt, this patch <https://gist.github.com/geertj/56425d0fdc7c54d4bc9f> needs to be applied to /usr/share/libvirt/cpu_map.xml. This patch forces the CPU type to be an Opteron G2 independent of the CPUID. To apply this patch, log on to the hypervisor in rescue mode <https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/5/html/Hypervisor_Deployment_Guide/sect-Deployment_Guide-Maintaining_and_Administrating_Red_Hat_Enterprise_Virtualization_Hypervisors-Setting_the_root_password.html>, apply the patch, and then issue the command “persist /usr/share/libvirt/cpu_map.xml”. This needs to be done after step 8 above. I ran into a small bug where the installation of the bootloader would run into a legacy SYSCALL instruction. The fix will be deployed soon. In the mean time, if the VM crashes when the installer is installing the bootloader, you should delay step #4 until after step #8. > On Sep 4, 2015, at 11:57 AM, Itamar Heim <ih...@redhat.com> wrote: > > On 09/04/2015 11:11 AM, Michal Skrivanek wrote: >> >> On 4 Sep 2015, at 16:58, Kyle Bassett wrote: >> >>> I am using Ravellosystems.com <http://Ravellosystems.com/> - we can >>> emulate SPM (AMD VT version) so you can run real hypervisors in the >>> cloud.
