xen host

I encountered many strange problems during the installation of xen in Ubuntu 12.04. As there are few online materials, I hope to provide them for your reference and avoid detours. The first is the basic installation process, which is roughly the same as that on the Internet. Refer 1. Install the required software packages for compiling Xen and Linux xen kernel: S

Use of Xen virtual machines (i) using virtual machine profiles and disk files to manually start the virtual machine system After the virtual machine system is created, the virtual system will start up and use the XM List command to see all the virtual machines that are started , but the next time we restart the system, we will not see the virtual machines created with the XM list . the network device for the virtual machine is not visible in the ne

To add a new system call to a Linux system, three steps are required:1. register a new system call number2. Update the system call table3. Add a new functionAdding a hypercall to xen is similar to adding a system call to Linux. The preceding steps are basically the same. Here is a specific example:For example, we want to add a hypercall for printing a message to xen. The parameter has a type of char *, whic

When using Xen virtual machines, we typically expose the virtual machine (DOMU) directly to the network in a bridging (bridging) way, just like a single server on the network, which is easy to use without any port forwarding in DOM0 without any iptable rules. However, in addition to bridging, Xen also supports the routing and NAT configuration of virtual machine networks. For example, we want to install 5 v

As a VPS service provider we need to ensure that each VPS fair use of the host (server) resources, to avoid a certain VPS due to program death cycle, hang, abuse and other factors "drag" other VPs, if this happens how to temporarily limit the VPS disk IO it? One way to do this is to limit the IO indirectly and imprecise by modifying the CPU weight of each virtual machine. The usual way to limit resources (CPU, memory, IO, etc.) on Linux is to use cgro
