description |
Starting with Linux kernel 4.10, the kernel does some sanity checking on the TSC_ADJUST MSR. Xen has implemented some support for that MSR in the hypervisor (Xen 4.3 and later) for HVM guests. But boot and secondary vCPUs are set up inconsistently. This causes the boot of a 4.10 HVM guest to hang early on boot.
This was fixed in the hypervisor by:
commit 98297f09bd07bb63407909aae1d309d8adeb572e
x86/hvm: do not set msr_tsc_adjust on hvm_set_guest_tsc_fixed
That fix would be contained in 4.6.5 and 4.7.2 and would be in 4.8.1 (not released, yet) which mean that Ubuntu 14.04/16.04/16.10 and 17.04 currently are affected. |

---
SRU Justification:
Impact: Without the TSC_ADJUST MSR fix, 4.10 and later kernels will get stuck at boot when running as (PV)HVM guests on Xen 4.3 and later.
Fix: Above fix either individually applied or as part of Xen stable stream (for Xen 4.7.x and 4.6.x) resolves the issue.
Testcase:
- Requires Intel based host which supports the TSC_ADJUST MSR
- Configured as Xen host
- HVM guest running Zesty/17.04
- Stuck at boot before, normal booting OS after |
