Two nics on HVM
by Jens Ahrens
Hello everybody,
I'm using FC7 and my server (IntelXeonQuad 64bit) provides 2 NICs. With
virsh-install I installed a (32bit RHEL3) HVM.
Until here everything runs fine.
When installing FC7, NIC1(eth0) got a public IP and NIC2(eth1) got a
private one.
When installing the HVM (RHEL3) only one NIC(eth0) exists, which got a
public IP.
The problem is that I also want the HVM to have a second NIC connected
to my private network (as in Dom0).
By default only one bridge (virbr0) is created.
brctl show gives:
eth0 8000.003048322dea no vif3.0
tap0
peth0
virbr0 8000.000000000000 no
How can I create a second one for (p)eth1 ?
By the way where does tap0 come from and what is it good for?
Thanks for any help.

FC8 (x86_64) host FC8 new virtual system install hangs
by Ted Toth
I'm using the Virtual Machine Manager to create a new virtual system. I
put the anaconda tree off of the DVD on an ftp server and point to it. I
allocate 500M of memory and 20G of disk in a file. The anaconda install
seems to go along fine until it starts to install packages and then it
hangs. Has anyone else experienced this? Are there any tricks to getting
this to work?

I created the file /var/lib/xen/images/rto-test.img by installing

Sir,
Subject :{1. Not able to load windows on xen enabled
kernel of RHEL 5
2.Able to load windows on xen enabled
kernel ON fedora 8 only on paralvirtulization mode.
3. Able to load RHEL 5 (DOM 1) on xen enabled

I am trying to load window 2000 SERVER Enterprise,
choosing Full Virtualized and after detecting hardware
at Windows Setup it is getting stuck.
With following message at the bottom "setup is

Can you help in this regard.
NOTE WITH RHEL 5 DVD I AM ABLE TO LOAD DOM 1

MBOARD IS gigbyte and vt is enabled in bios and

xm create -c recovery fails
by John Summerfield
I'm running F8, xen-3.1.2-1.fc8, 2.6.21.7-2890.fc9xen.
I have a xen configuration which contains this stanza:
disk = [ 'file:/var/lib/xen/images/recovery.img,hda,w'
, 'file:/var/lib/xen/images/WindowsXP.img,hdb,w'
# , ',hdc:cdrom,r'
, 'phy:hda,ioemu:hdd,r'
]
If I comment out the line containing "'phy:hda,ioemu:hdd,r' then the xm create
line works and the guest starts up and runs fine. Whether I have "ioemu"
doesn't make any obvious difference, google suggested it.
With the stanza as above, it fails:
[root@potoroo ~]# time xm create -c recovery
Using config file "/etc/xen/recovery".

CPU management
by Augusto Castelan Carlson
Hi!
I will have servers with different CPU specification:
Quad core, dua core, one core.
Each core appears as one VCPU for xen?
How the management works when there is only one core, dual core and quad core?
Suppose that I have 2 guests and for the quad core processor I give 2
VCPU to the dom0 and one for each domU. How it is managed? If DomU
needs more CPU, it can use idle CPU from Dom0? If DomU is using idle
CPU from Dom0 and Dom0 starts to need CPU, it will have their slice
back?
Thanks in advance.
Regards,

where is XEN/VM networking defined?
by Fulko Hew
I've just started playing with virtualization on F8
and (amongst other things...) I'm having a hard time
figuring out:
a) what I need to do to get IP networking properly
working between VMs and the outside world.
b) where/what networking scripts/config files are VM
related, and that are run at system startup time,
or even VM startup time???
c) what are my options for VM-to-world networking?
d) what options/techniques does:
'System->Virtual Machine Manager' choose when
reconfig'ing the host system and defining how
the VM is started/connected.
I'm specifically interested in QEMU based VMs, because:
a) I don't have the hardware for KQEMU based VMs,
b) I haven't been able to figure out how to build
a XEN based VM either.
So when running my QEMU based VMs I'm (currently)
just booting a std kernel, not the XEN based kernel.
I've tried RTFM'ing and I've tried searching back a few
months on this list for clues, and haven't (yet) found
a description of the networking options, or how or what
I need to do to get it to work properly. Is there a
good HowTo somewhere?
TIA

virt* source
by John Summerfield
I've checked out the source virt*, but I cannot tell that it's newer
than I have.
The changelog for virt-manager suggests not.
Mercurial doesn't set file times to those on the server, so they reflect
when I checked it out rather than what's in the repo.
I planned to build from source and install to /usr/local, but this
suggests my idea is impractical:
virtinst--devel/virtinst/ParaVirtGuest.py: cmd =
["/usr/bin/virsh", "console", "%s" %(self.domain.ID(),)]
Surely, the location of executable components should not be hard-coded
in the source tree. I could live with it, grudgingly, if it was set at
configure time.
