[PATCH v2] xen: fix initialization of wallclock time for PVHVM on migration
Call update_domain_wallclock_time on hvm_latch_shinfo_size even if the bitness of the guest has already been set, this fixes the problem with the wallclock not being set for PVHVM guests on resume from migration.

[PATCH] x86/vtsc: update vcpu_time after hvm_set_guest_time
When using a vtsc, hvm_set_guest_time changes hvm_vcpu.stime_offset, which is used in the vcpu time structure to calculate the tsc_timestamp, so after updating stime_offset we need to propagate the change to vcpu_time in order for the guest to get the right time if using the PV clock. This was not done correctly, since in context_switch update_vcpu_system_time was called before vmx_do_resume,

[PATCH 0/2] libxl/xl: two more coverity related fixes
The first patch is a leftover from the switch to libxl__create_qemu_logfile, and while there it also handles possible errors when opening /dev/null. The second one is a fix for the issues present in do_daemonize. Thanks, Roger.

pygrub/hvm boot with alternate script= for block devices
Hi, I am doing some experimentation with xen and Ceph and have a problem booting my guest when my disk = [] uses an alternate block script. Installation from a .iso was ok since the boot device was a file but now trying to boot from the rbd neither the hvmbuilder or pygrub can start as they treat the first value after target= as the /dev node to try and use. My disk parameter looks like: disk =

[PATCH RFC v2] pvh: clearly specify used parameters in vcpu_guest_context
The aim of this patch is to define a stable way in which PVH is going to do AP bringup. Since we are running inside of a HVM container, PVH should only need to set flags, cr3 and user_regs in order to bring up a vCPU, the rest can be set 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

[PATCH] xen: fix initialization of wallclock time for PVHVM on migration
The initial values of the wallclock time in the shared info page are set for PVHVM guests when the hypercall page is initialized, since the hypercall page is not reinitialized on resume, the hypervisor wallclock time is not properly set on resume. Fix it by forcing an update of the wallclock values when the shared info page is mapped. Signed-off-by: Roger Pau Monné <roger.pau@citrix.com>

[PATCH] tools: revert to using /var and /etc/
26470:acaf29203cf9 "tools+stubdom: install under /usr/local by default" moved more stuff under /usr/local than was desirable. In particular SYSCONFIG_DIR (configuration for initscripts) moved to /usr/local/etc/{sysconfig,defaults} while the initscripts themselves (correctly) remained in /etc/init.d. Moving /etc/xen/scripts breaks the udev bakcned rules file. Lastly stuff under /var was

qemu-xen qdisk performance
Hello, I''ve recently setup a Linux Dom0 with a 3.0.17 kernel and Xen 4.1.2, and since the 3.x series doesn''t have blktap support I''m using qdisk to attach raw images. I''ve been playing with small images, something like 1GB, and everything seemed fine, speed was not fantastic but it was ok. Today I''ve set up a bigger machine, with a 20GB raw hdd and the
