[BUG] Not exiting media forced a promptly close of libvirt 3.10
Hello, In the .xml file I use a media which is no longer available. In the past, I got the information media not available and the creation of the VM was stopped - O.k. behavior.

Quantifying libvirt errors in launching the libguestfs appliance
As people may know, we frequently encounter errors caused by libvirt when running the libguestfs appliance. I wanted to find out exactly how frequently these happen and classify the errors, so I ran the 'virt-df' tool overnight 1700 times. This tool runs several parallel qemu:///session libvirt connections both creating a short-lived appliance guest. Note that I have added Cole's

maxvcpus
Hi list, According to the libvirt documentation [1] "Show maximum number of virtual CPUs for guest domains on this connection" This may not be a complete definition. My first guess from the above was that this returns the number of virtual CPUs that can exist at the same time on the host, either one or several VMs. In fact it returned 16 in my fedora 20 desktop running with KVM,

How to activate all VPCUS for a domU?
Hi, I have set maxvcpus and vcpus options in my domU configuration file, and I can see that X number of vcpu are set for the domU. I tried to activate all the vpcus by using vpcu_avail option (using decimal to represent vpcu bitmask e.g. 24=11000) but it doesn''t seem to work, and only the first vpcu is activated (i.e. has -b- state) while all other vpcu''s set for the domU are

[PATCH 1/2] S390: take a full byte as ext_param indicator
Currenty the ext_param field only distinguishes between "config change" and "vring interrupt". We can do a lot more with it though, so let's enable a full byte of possible values and constants to #defines while at it.

[PATCH] Fix QEMU HVM hotplug race in QEMU traditional (Xen 4.1, Xen 4.2, and Xen 4.3) (v1).
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

Changing <on_reboot> in the domain XML file
Using virsh edit, I made the following change to the domain XML file: <on_reboot>destroy</on_reboot> But this appears to do nothing. The VM guest is Windows 10, and when directing it to reboot, it still reboots, instead of shutting off the VM. I was trying to work around some kind of a bug, somewhere, that started happening after updating to Fedora 26 and qemu 2.9, where a
