[Xen-devel] Only CPU0 active after ACPI S3, xen 4.1.3

[Marek Marczykowski <marmarek@xxxxxxxxxxxxxxxxxxxxxx>]

Hi all,

After resume from ACPI S3 system has only CPU0 enabled, every vCPU from every
domain works on CPU0 [1].  When trying to pin some vCPU to CPU1 got error:
xl vcpu-pin testvm 1 1
libxl: error: libxl.c:2565:libxl_set_vcpuaffinity setting vcpu affinity:
Invalid argument

What went wrong? How can I reenable CPU1-CPU3?

System info:
xen 4.1.3
linux 3.4.18 with acpi-s3 patches from Konrad's git
Processor: Intel i5-2520M

dmesg from dom0 and hypervisor attached.

BTW Are there any plans to upstream acpi-s3 patches?
