`memset(&mc_ext, 0, ...)'' leads to a buffer overflow and a subsequent null pointer dereference. Replace `&mc_ext'' with `mc_ext''.

Xen/MCE: vMCE injection In our test for win8 guest mce, we find a bug that no matter what SRAO/SRAR error xen inject to win8 guest, it always reboot. The root cause is, current Xen vMCE logic inject vMCE# only to vcpu0, this is not correct for Intel MCE (Under Intel arch, h/w generate MCE# to all CPUs). This patch fix vMCE injection bug, injecting vMCE# to all vcpus. Signed-off-by: Liu,

Hi there! I just fresh-installed Xen on new server, Xeon E5-2620, and noticed following thing: node1 ~ # xl info -n host : node1 release : 3.8.8 version : #1 SMP Tue Apr 23 20:54:17 MSK 2013 machine : x86_64 nr_cpus : 6 max_cpu_id : 5 nr_nodes : 1 cores_per_socket : 6 threads_per_core

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -

Hi Folks: I run into a problem when enabling Xen in next generation server platforms with Xen c/s is 21380. Xen reported "CPU Not responding" when booting up 32 CPUs( 2 sockets with 8 cores/16threads total). The log files belonging showed something wrong with APCI. So I added x2apic=0 in the xen grub line, but the symptom remained. However, Native RHEL5.5 can

Hi, This is updated xen vMCE design foils, according to comments from community recently. This foils focus on vMCE part of Xen MCA, so as Keir said, it''s some dense. Later Will will present a document to elaborate more, including Intel MCA and surrounding features and Xen implementation. Thanks, Jinsong

Hey, Are there any known issues with the Intel''s integrated HD graphics 4000? I just bought a new laptop and have tried everything I can think of to get Xen to load. After choosing Xen in GRUB, it just boots to a black screen. There is no error message , no dmesg output, nothing. I have no idea what is causing this problem. I''ve gotten Xen to install with no problems on another
