I am trying to setup the Jailhouse hypervisor on an Intel Xeon x86_64 system. However, the hypervisor gets stuck when writing to the MSR_IA32_PAT during the initial setup. Apparently, the value that is written to the MSR_IA32_PAT is not valid (same values is used across different systems by Jailhouse). It works on an older system but not on the current one.
