Hi,
I''m having IPv6 problems with my CentOS 5.2 dom0 while the same
NetBSD/i386 5.0
domU running on Debian 5.0 dom0 works as expected. CentOS is running
gitco''s Xen
3.3.1 packages and Debian is running self-compiled Xen 3.3.1.
My dom0 kernels:
# uname -srm
Linux 2.6.18-92.1.22.el5xen x86_64
# uname -srm
Linux 2.6.18.8-xen x86_64
My domU configuration file:
name = ''p140''
memory = 512
kernel = ''/var/tmp/netbsd-XEN3PAE_DOMU.gz''
disk = [ ''phy:/dev/iscsi/p140,sda,w'' ]
vif = [ ''mac=00:16:3e:01:40:01, bridge=vlan2000'' ]
My vlan2000 interface:
# brctl show | grep vlan2000
vlan2000 8000.0015c5fc2806 no eth1.2000
# ifconfig eth1.2000

domU on CentOS dom0
-------------------
# sysctl -w net.inet6.ip6.accept_rtadv=1
net.inet6.ip6.accept_rtadv: 0 -> 1
# rtsol xennet0
(wait for a moment)
# ifconfig xennet0
xennet0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu
1500
capabilities=2800<TCP4CSUM_Tx,UDP4CSUM_Tx>
enabled=0
address: 00:16:3e:01:40:01

domU on Debian dom0
-------------------
# sysctl -w net.inet6.ip6.accept_rtadv=1
net.inet6.ip6.accept_rtadv: 0 -> 1
# rtsol xennet0
(wait for a moment)
# ifconfig xennet0
xennet0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu
1500
capabilities=2800<TCP4CSUM_Tx,UDP4CSUM_Tx>
enabled=0
address: 00:16:3e:01:40:01
inet6 fe80::216:3eff:fe01:4001%xennet0 prefixlen 64 scopeid 0x1
inet6 2001:xxxx:xxxx:xxxx:216:3eff:fe01:4001 prefixlen 64
So, there''s no IPv6 traffic when the domU is running on CentOS dom0.
Any ideas?
