The concept of running a virtual machine, KVM-based, in this case, under RHCS is acceptable and reasonable. The interesting part is that the <vm/> directive replaces the <service/> directive and acts as a high-level directive for VMs. This allows for things which cannot be performed with regular ‘service’, such as live migration. There are probably…
In my post here, I have explained (actually – created a shell script) to map USB disks to VMs directly. While this is easy and simple, it becomes more challenging when you want to map internal SATA disks. They are not attached to the “Removable Storage” SR, and thus, behave differently. The solution is to…
There is a very nice script for Windows dealing with attaching XenServer USB disk to a guest. It can be found here. This script has several problems, as I see it. The first – this is a Windows batch script, which is a very limited language, and it can handle only a single VDI disk…
In the past I hacked around a problem with the order of starting (and with several bugs) a network stack combined of network bonding (teaming) + VLAN tagging, and then with network bridging (aka – Xen bridges). This kind of setup is very useful for introducing VLAN networks to guest VMs. This works well on…
This is a tricky one. I have had to waste a lot of time. The trick is to use 32bit browser (extract firefox into $HOME/firefox and run it from there. Details below), and a full JDK package from Sun. JRE is not good enough! I have a $HOME/bin/firefox32 script which looks like this: #!/bin/bash exec…
Unlike previous versions, VMs do not have a visible property in the GUI allowing autostart. This has been claimed to collide with the HA function of the licensed version. While I believe there is a more elegant way of doing that (like – ignoring this property if HA is enabled), the following method can allow…
