Ok, I reran the install and got the exact same result.  No bootup or
no console output at least.

Just because you passed those kernel command line options in for install
doesn't mean they will stick for the life of the VM. You will need to
find a
way to edit the grub.conf in the guest to get bootup output, and then
/etc/inittab to start a TTY on the serial line.
I thought I had done this because I added the console args to the
kernel line during the installation screens so I assumed it would
generate a grub.cfg(grub2) using them.  I guess that still wasn't enough.

You'll either need to set up temporary graphical access, find the IP
of the VM
and use ssh, or some way to kernel boot into rescue mode (or hack up
your own
boot.iso to append custom kernel args).
Yes, I need to figure out how to get a text-based rescue session
running for the VM.

Here is the process line:
root     23068     1  0 20:46 ?        00:00:02 /usr/bin/kvm -S -M
pc-0.11 -m 2048 -smp 4 -name DOMAIN-1 -uuid
b1620075-a0ba-1246-fd67-1243c20870a6 -nographic -monitor
unix:/var/run/libvirt/qemu/DOMAIN-1.monitor,server,nowait -boot c
file=/var/lib/libvirt/images/DOMAIN-1.img,if=ide,index=0,boot=on -net
nic,macaddr=54:52:00:4b:f1:a6,vlan=0,name=nic.0 -net
tap,fd=17,vlan=0,name=tap.0 -serial pty -parallel none -usb

I see it has both -monitor and -serial.  Does that make any

I tried running the command directly and here is what it outputs:
TUNGETIFF ioctl() failed: Bad file descriptor
TUNSETOFFLOAD ioctl() failed: Bad file descriptor
char device redirected to /dev/pts/1

You can't run the generated command directly because libvirtd sets up
like tap devices before running the guest.

I checked both the image file and the .monitor file and both are there
and readable so I don't understand what file it is complaining about.

It's complaining about the tapfd, which isn't present because libvirt
takes care of it.
Ok, understand that.  Thanks.

I tried starting the VM in graphical env with virt-manager.  The VM
never starts and throws this error:
Traceback (most recent call last):
 File "/usr/share/virt-manager/virtManager/engine.py", line 493, in
 File "/usr/share/virt-manager/virtManager/domain.py", line 573, in startup
 File "/usr/lib64/python2.6/site-packages/libvirt.py", line 287, in create
   if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: internal error Domain DOMAIN-1 didn't show up

So it doesn't look like this is a guest distro issue.  How can I track
down what is wrong?

See if there are any errors in /var/log/libvirt/qemu/<vmname>.log. See if
disabling selinux (setenforce 0) helps at all.

Ignore the Trackback. Found a typo in my xml that I used to define the domain.

Now when I try to start the guest in virt-manager it says "Console not configured for guest". I guess my console args didn't get into grub.cfg.

So I'm back to trying to boot a rescue kernel.
