The existing xc_domain_dumpcore is very specific to disk/file based output. Refactor the code slightly to allow more user-specified control. This is done by adding a parallel xc_domain_dumpcore2 (naming isn''t always my strong suit), which allows the specification of a callback routine and an opaque argument block. Th...

Hi, In the case of linux, crash_kexec() is occured by "sysrq c". In the case of DomainU on xen, Help is occured by "sysrq c" now. So The way of dumping DomainU''s memory manualy is nothing. I fix this issue by the following way. 1. Panic is occured by "sysrq c" on both Domain0 and DomainU. 2. On DomainU, coredump is generated in /var/xen/dump (on Domain0).

This patch allows core-dumping to work on a cross-bit host/guest configuration, whereas previously that was not supported. It supports both PV and FV guests. The core file format generated by the host, needs to match that of the guest, so an alignment issue is addressed, along with the p2m frame list handling being done according to the guest size.

I''ve put together two patches. The first introduces a new dom0_op, set_max_vcpus, which with an associated variable and a check in the VCPUOP handler fixes [1]bug 288. Also included is a new VCPUOP, VCPUOP_create, which handles all of the vcpu creation tasks and leaves initialization and unpausing to VCPUOP_initialize. The separation allows for build-time allocation of vcpus which

Hello, I am trying to see if the hypervisor can be used to detect deadlocks in the guest VMs. My goal is to detect if a guest OS is deadlocked, and if it is, then create a clone of the deadlocked OS without the locking condition, and letting the clone run. While the clone runs I am hoping to generate some hints that could tell me what caused the deadlock. I simulated a deadlock/hang
