Tuesday, January 5th, 2010Red Hat RHEL 5 KVM & Xen unconfusion !
Friday, September 25th, 2009now includes full support for the Kernel-based Virtual Machine (KVM) hypervisor on x86_64 based architectures. KVM is integrated into the Linux kernel, providing a virtualization platform that takes advantage of the stability, features, and hardware support inherent in Red Hat Enterprise Linux.
Note
Xen is the default hypervisor that is shipped with Red Hat Enterprise Linux. As such all configuration defaults are tailored for use with the Xen hypervisor. For details on configuring a system for KVM, please refer to the Virtualization Guide.
Important
Xen based virtualization is fully supported. However, Xen-based virtualization requires a different version of the kernel to function. The KVM hypervisor can only be used with the regular (non-Xen) kernel.
Warning
While Xen and KVM may be installed on the same system, the default networking configuration for these are different. Users are strongly recommended to only install one hypervisor on a system.
Red Hat defends replacing Xen with KVM
Thursday, June 26th, 2008Red Hat RHEL, CentOS, OEL 4 & 5 SAN filesystems go readonly !
Wednesday, June 11th, 2008Apparently there is a problem in the kernel used in Red Hat RHEL 4&5, CentOS 4&5, OEL 4&5, SUSE, Ubuntu 7 and other GNU/Linux distributions that causes EXT2 EXT3 filesystems that are residing on SANs to randomly go read-only !
However if you are using kernel 2.6.18-53.1.21+ or 2.6.22+ you should be ok !
