| + | =====RedHat 6 PV domU ===== | ||
| + | RHEL6 runs as Xen PV (paravirtual) domU using the pvops framework in the default kernel. | ||
| + | |||
| + | A convenient way to make the raw image for domU usage is with KVM. Install from the CDrom, the usual way. | ||
| + | To use this image as a domU, edit the /etc/grub.conf in the image (by using KVM) and add to the kernel line: | ||
| + | |||
| + | console=hvc0 | ||
| + | |||
| + | After this, this machine will not have a console with KVM anymore when rebooted in KVM. So shut it down, and copy it over to the xen dom0 machine. | ||
| + | |||
| + | |||
| + | A minimal domU.conf file example is: | ||
| + | |||
| + | name = "rh6beta" | ||
| + | memory = 1024 | ||
| + | vcpus = 2 | ||
| + | bootloader = "/usr/lib/xen-4.0/bin/pygrub" | ||
| + | disk = [ "phy:/dev/mapper/vg00-rh6disk0,xvda,w" ] | ||
| + | vif = [ "mac=00:16:34:f2:3b:7f,bridge=xenbr3"] | ||
| + | extra = "clocksource=jiffies" | ||
| + | |||
| + | |||
| + | When the mac-adres of the domU has changed, update the configfiles: | ||
| + | * /etc/sysconfig/network-scripts/ifcfg-eth* (HWADDR=... ) | ||
| + | * /etc/udev/rules.d/70-persistent-net.rules | ||
