Following an email found in the list archive to setup serial port
access for VM, I'm having some trouble. I wonder if something has
changed since 2008?
1) I have xencons=off as a kernel arg for dom0, and when dom0 boots,
it finds the serial port.
2) I have blacklisted 8250, 8250_pnp and serial_core, rebooted, no
serial port under dom0
3) added the following to my domu config (domu is 32bit centos 5.2, pvm)
addirq = [ 4 ]
ioports = [ "3f8-3ff" ]
4) now to start the vm and see what happens:
# xm create mythserver
Using config file "./mythserver".
Error: function takes exactly 4 arguments (3 given)
My host is 64 bit centos 5.2, domu is 32 bit centos 5.2. I'm running
the stock redhat version of xen that ships with el5.2
Any suggestions?
