Hi

using a vnic in the kvm Guest.

Quick question, if I may, in the zone do you have vnic1 plumbed? If you do
then there will be issues with the same MAC address used in the zone _and_
the KVM instance which wants to believe it is it's own machine.
You will always be better off passing in a second virtual nic just for the
KVM it you decide to run KVM in a zone.

Hi all,
This post is around running a KVM inside a Zone and trying to get the
networking working. I hope some of you have a working config and any help
is appreciated. Although networking in the Zone is working fine, I cannot
seem to connect in the KVM running inside it. I'm def missing a
networking/routing issue here.
I am sure this is the standard setup (output shortened for brevities sake):
1. Global Zone's network interfaced. We're using vnic1 for the Zone
# dladm show-vnic
LINK OVER SPEED MACADDRESS MACADDRTYPE VID
net0 igb0 1000 2:8:20:4:5e:e1 random 0
net1 igb0 1000 2:8:20:d:5b:d2 random 0
vnic1 igb0 1000 2:8:20:d8:ad:72 random 0
## using this VNIC
2. Zone setup. The Zone has exclusive rights to the physical
interface (vnic 1)
# zonecfg -z src info
zonename: src
zonepath: /naspool/zones/src
brand: ipkg
autoboot: true
bootargs:
pool:
limitpriv:
scheduling-class:
ip-type: exclusive
hostid:
fs-allowed:
net:
address not specified
allowed-address not specified
physical: vnic1
defrouter not specified
device:
match: /dev/kvm
device:
match: /dev/zvol/rdsk/naspool/zones/src/kvm
dataset:
name: naspool/zones/src/kvm
3. The startscript for the KVM:
#!/bin/ksh
MAC=$(dladm show-vnic -po macaddress vnic1)
/usr/bin/qemu-kvm \
-boot cd \
-cpu host \
-enable-kvm \
-vnc 0.0.0.0:43 \
-smp 4 \
-m 8192 \
-no-hpet \
-localtime \
-drive
file=/dev/zvol/rdsk/naspool/zones/src/kvm/disk0,if=ide,index=0 \
-drive
file=/naspool/zones/src/kvm/iso/sol-11_3-text-x86.iso,media=cdrom,if=ide,ind
ex=2 \
-net nic,vlan=0,name=net0,model=e1000,macaddr=$MAC \
-net vnic,vlan=0,name=net0,ifname=vnic1,macaddr=$MAC \
-vga std
The KVM (Solaris 11) start fine and the installation goes through without a
hitch (quite fast to be honest, very good performance). However I cannot
connect to it from the outside. The KVM host I have configured with an IP
but cannot ping it, or from the KVM itself cannot see the default gw.
However traffic to/from the Zone is working fine. Running a KVM in the
Global Zone works a treat, however inside a Zone I am definitely missing a
step in getting the routing from the KVM to the Zone sorted.
Any help appreciated. Thanks for your time.
Regards,
Jacques
