I‘m running a KVM virtual machine (FreeBSD 7 and Fedora Linux 13 desktop) under Redhat Enterprise Linux 5.5. However, I’m not getting the remote access via VNC (Virtual Network Computing) to access my Fedora Linux graphical desktop or FreeBSD console. How do I turn on VNC support without reinstalling both operating systems?
OpenBSD version 4.5 and above made changes in kernel which prevents booting OpenBSD using KVM technology. OpenBSD 4.4 runs with mbbios enabled. However, due to some sort of bug in KVM it does not boots. The workaround is to disable mpbios. This may or may not happen with your installation.
OpenBSD is a UNIX like system based on Berkeley Software Distribution (BSD). It was forked form NetBSD and created by Theo de Raadt in 1995. OpenBSD is famous for quality code and documentation without compromising position on software licensing. OpenBSD is also well know for focus on security features such as Memory protection, cryptography, randomization and much more in default base installation.
There are various ways to start virtual machines at at boot time. This means you don’t have to type virsh start vmName command. This can be done by marking a vm as autostart.
The virtual network (virbr0) used for Network address translation (NAT) which allows guests to access to network services. However, NAT slows down things and only recommended for desktop installations. To disable Network address translation (NAT) forwarding type the following commands:
KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions Intel VT or AMD-V. How do I install KVM under CentOS or Red Hat Enterprise Linux version 5.5?

I‘m using KVM to run multiple virtual machines under Redhat Enterprise Linux server 5.5. I’ve installed FreeBSD 7.x 64 bit as guest operating systems. How do I redirect the FreeBSD version 6, 7 or 8 virtual machine console to a serial port using virsh console command for management purpose from host itself?
