Dear ALL: XEN 4.1.2/4.1.3 failed to save centos6.2 HVM guest(with PV drivers) After save finished, the guest is halt with following errors: ---------------------------------------------------------------- Pm_op(): platform_pm_thaw+0x0/0x50 returns -19 PM: Device i8042 failed to thaw: error -19 ------------------------------------------------------------------ In my test, this happends when the guest os is centos 6.2 & centos 6.4, maybe for all the centos 6 series OS HVM guest with PV drivers....

These patches update the example FLASK policy shipped with Xen and enable its build if the required tools are present. The third patch requires rerunning autoconf to update tools/configure. [PATCH 1/3] flask/policy: sort dom0 accesses [PATCH 2/3] flask/policy: rework policy build system [PATCH 3/3] tools/flask: add FLASK policy to build

...oint on Xen. The Linux Xen guest can be saved the state to restore later, and also created snapshot like checkpoint via the hypervisor. But, when the snapshot is created for the PV guest, it will hangup. We added ''PMSG_CANCEL'' message and ''cancel'' handler in dev_pm_ops struct in the pm-linux part. In creating checkpoint mode, the resume handler of xenbus should not be called. In this case, it is recognized that the suspend was canceled in drivers/xen/manage.c and call dpm_resume_end() with PMSG_CANCEL. If the ''cancel'' handler is defined, it is...

Hello, The following patches are a solution to a problem we have encountered when using the Xen hypervisor: - Need Pxx/Cxx states to save on power consumption when using Xen (we do want those datacenters to consume less power!), - Also need to figure out the Turbo mode so that the scheduler can properly boost a core for CPU bound guests. In essence the Xen hypervisor requires that
