It is possible to run Xen alongside other OSes. It would be just another boot option. Xen is usually installed on an ordinary OS to become a control OS called a Dom0. If you choose, a Dom0 can be your Ubuntu. Or it can be a separate installation on another partition, that is, another OS like Ubuntu with Xen on it in your system depending on your choice. To ...

Yes, sure. Add to kernel command line: root=host rootfstype=9p rootflags=trans=virtio And you may boot without initrd.

I manage to fix the issue after I installed manually an older version (v1.14.0) of libiscsi where qemu could find the libiscsi.so.4 file. First I removed the v1.17.0-2 installed with pacman sudo pacman -Rddn libiscsi without uninstalling the qemu-block-iscsi dependency. I cloned the source code from github sahlberg/libiscsi and after the build I ...

Virtual interfaces do not artificially limit throughput to a particular data rate, like a physical interface would. However, they do incur software overhead, so you should expect transfer rates to be lower compared to simpler inter-process communication mechanisms, unless the bottleneck is some other factor.

At the time of writing all motherboards seem to have a (beta)bios available supporting the IOMMU. Although 970 chipset itself looks to be supporting ...

A workaround to the situation appears to be to toggle the link state of the VM right after starting it, i.e. on the command line do: $ VBoxManage startvm <vmid> $ VBoxManage controlvm <vmid> setlinkstate1 off $ VBoxManage controlvm <vmid> setlinkstate1 on

Typically virtual box and VMware both configure the network connection to the vm via the host to be NAT based, on an isolated subnet from the the test of the LAN. This has the benefits and drawbacks of the NAT implementation on most peoples home routers. You aren't 'visible' to the network/internet unless you initiate the traffic or configure port ...

Each RUN line in a Dockerfile gets executed as the only process in a container. The command you are running, mysql_install_db --verbose && /usr/bin/mysqladmin -u root password 'password', attempts to communicate with an already running mysql/mariadb server. Since this is the only thing running in the container, and there is no mysql service running, ...

Google says this is a known bug. The recommended fix from that bug seems to be to use a (more) recent version of libvirt and virt-viewer, but there's no evidence that this will help.
