Hi, (Assume VPID is available and enabled.) I''m trying to figure the TLB stuff with VPIDs. I understand from the poorly written chapter in the intel manual that if an HVM vcpu is running then only the TLBs tagged with the vcpu.VPID will be used. If xen or a PV guest is running, then VPID 0 TLBs are what will be used. Now I understand the hvm_asid_flush_vcpu upon new guest cr3, will

We use XENMEM_add_to_physmap_range which is the preferred interface for foreign mappings.

Hi Guys, Thanks for the interest in the xen hypervisor debugger, prev known as kdb. Btw. I''m gonna rename it to xdb for xen-debugger or hdb for hypervisor debugger. KDB is confusing people with linux kdb debugger and I often get emails where people think they need to apply linux kdb patch also... Anyways, attaching patch that is cleaned up of my debug code that I accidentally left in

...and 2 implement changes in and around construct_dom0. Patch 7 adds option to boot a dom0 in PVH mode. The rest support tool stack on a pvh dom0. These patches are based on c/s: 4b07b3cbf29f66da6090d52e75b5fdae592c6441 These can also be found in public git tree at: git://oss.oracle.com/git/mrathor/xen.git branch: dom0pvh-v6 Thanks for all the help, Mukesh

Trying to migrate a 64bit PV guest with 64GB running medium to heavy load on xen 3.4.0, it is showing lot of soft lockups. The softlockups are causing dom0 reboot by the cluster FS. The hardware has 256GB and 32 CPUs. Looking into the hypervisor thru kdb, I see one cpu in sh_resync_all() while all other 31 appear spinning on the shadow_lock. I vaguely remember seeing some thread on this while

...once the vCPU is started using the bare metal methods. Additionally, the guest can also set cr0 and cr4, and those values will be appended to the default values set by Xen.

Hi Ian/Stefano: I changed over to the PV clock for hybrid liked we talked at the hackathon. I still have the hang in update_wall_time() after dom0 switches to xen as clocksource. The source of hang seems to be in xen stime_local_stamp in cpu_time that suddenly jumps to a large 64bit value. I''ve been chasing to figure where that happens, and why for the hybrid and not PV. It appears the

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his m...

Hi, I''m looking at a system hang on a large box: 160 cpus, 2TB. Dom0 is booted with 160 vcpus (don''t ask me why :)), and an HVM guest is started with over 1.5T RAM and 128 vcpus. The system hangs without much activity after couple hours. Xen 4.0.2 and 2.6.32 based 64bit dom0. During hang I discovered: Most of dom0 vcpus are in double_lock_balance spinning on one of the locks:
