Hi everyone, I''m making a user application that''s going to run in Xen guests (both dom0 and domU) and each instance needs to read values from the VM''s unique space in XenStore. The way I have done it is use the functions defined in <xs.h> using the xs_read function to read a value. In command line I''m able to use the xenstore-read program and simply pass an argument like ''domid'' or ''vm'' without having to specify an absolute path, it will read the value in /local/domain/DOMID/ and I don''t need to w...

Hey Ian and Stefano, Please see this thread: http://lists.xen.org/archives/html/xen-devel/2013-05/msg01053.html for the debug patches and some of the discussion. These three patches fix an race that has been in QEMU traditional for a long time. The guts of the bug is that if you have a guest with these options: vcpus=1 maxvcpus=32 and do ''xl vcpu-set <guest> 32'' the

Hi, everyone! I am working on xen-4.2.0 with spice remote connect. My host is Fedora 14 and guest is win7. I have installed spice package and now I can connect to guest by spice client. For better graphics experience, I want to try the VGA passthrough. With spice tool, I have to create a VM by xl command, and now I am wondering if it supports VGA passghrouth? If so, how should I test it ?
