Forcibly Remove Storage Devices From XenCenter via CLI
This is my second post in focused on forcibily something from XenCenter, as apparently XenCenter has a hard time knowing when to "forget" a device or host on its own. Now while this is annoying, it can be resolved rather easily from the command line. Now, lets take a step back and reflect for a … Continue reading Forcibly Remove Storage Devices From XenCenter via CLI
Cloning A Virtual Machine in KVM
KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). More Information here. KVM is now native to RHEL/Centos and has replaced Xen in RHEL 5.4. What i have seen so far has been pretty interesting, but I have barely scratched the surface … Continue reading Cloning A Virtual Machine in KVM
Overview of RedHat Virtualization
