Hi, after migrating to libvirt/libxl according to: https://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt I've noticed that my Xen PV domains are being launched by qemu-system-i386 running under root privileges. I am wondering why is this? Previously no qemu process was used. If qemu is needed for some reason, are there any guidelines for non-root operation? Thanks -- Karel Hendrych

...don't find any solutions on the net. I hope, you can help me. The problem is that I can't connect to my vm desktop with Virt-Viewer. I follow the installation guide available for centos?: http://wiki.centos.org/HowTos/Xen/Xen4QuickStart and http://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt My CentOS is a fresh new install 6.5 with xen 4.2 and X11. >From Dom0, when I launch virt-manager, everything is ok. I can create a new vm and the first time I connect to the virtual graphics without any problems. But, if I close the desktop VM, I can't access anymore to the virtual deskto...

...are recommended? You can use virt-manager either from the Dom0 server (if it has all the GUI stuff and virt-manger installed) ... OR ... by connecting to the Dom0 using virt-manager from a Linux workstation. See my xen4centos libvirt article here: http://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt You can also use Xen XM tools with the default install ... OR ... if you do not plan on using libvirt at all, you can setup and use Xen XL tools (if using libvirt, you have to use xend and Xen XM): XM Tools: http://wiki.xen.org/wiki/XM XL Tools: http://wiki.xen.org/wiki/XL Thanks, Johnny Hughes...

...we want to use Xen to host paravirtualised guests (the system has no hardware virtualization support). To manage the domain we would like to use libvirt. Xen and libvirt are set up as described here: http://wiki.centos.org/HowTos/Xen/Xen4QuickStart http://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt When we try to create a new domain this does not work.

...#39;m trying to install libvirt for xen on a brand new, minimal installation of CentOS 7.5.1804. After installing the OS, I did a 'yum update' and followed the basic how-tos at https://wiki.centos.org/HowTos/Xen/Xen4QuickStart and https://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt From previous experience, I know that the above steps worked fine.

I normally use the network-script parameter in the '/etc/xen/xend-config.sxp' configuration file to configure network bridges. However, the latest release of Xen4CentOS (which comes with Xen 4.4.1) has xend disabled by default. Can I continue to use network-script without xend? If not what is the recommended method for automatically configuring network bridges with the latest release of

Hi, I have used this http://wiki.centos.org/HowTos/Xen/Xen4QuickStart and everything works like a charm then I installed a VM using http://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt only to realize later that I don't want NAT. I would want to use PCI passthrough and so i used virsh net-destroy default virsh net-undefine default and net-create /home/kartik/passthrough.xml net-autostart passthrough net-start passthrough here is the output of /etc/libvirt/qemu/networks/passth...

The subject says it all. I got CentOS 6.4 installed and then converted it to boot into the Xen kernel, using the C6.4 system as its dom0. But now I'm uncertain how to put a C6.4 domU on the result. Which tools are recommended?
