[Qemu-devel] IPv6 gets removed on bridge

[Raps, Markus (centron GmbH)]

Hi,

i have a short question iam using proxmox and my ipv6 settings gets removed 
every time  a vm is added to the bridge.

So can you confirm this function/bug/behavior?

Before VM starts
~# sysctl -qa 2>/dev/null  | grep 'disable_ipv6'
net.ipv6.conf.all.disable_ipv6 = 0
net.ipv6.conf.bond0.disable_ipv6 = 1
net.ipv6.conf.bond0/102.disable_ipv6 = 1
net.ipv6.conf.bond0/605.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 0
net.ipv6.conf.eth0.disable_ipv6 = 0
net.ipv6.conf.eth1.disable_ipv6 = 0
net.ipv6.conf.eth2.disable_ipv6 = 0
net.ipv6.conf.eth3.disable_ipv6 = 0
net.ipv6.conf.lo.disable_ipv6 = 0
net.ipv6.conf.tun0.disable_ipv6 = 0
net.ipv6.conf.vmbr0.disable_ipv6 = 0
net.ipv6.conf.vmbr0v102.disable_ipv6 = 0
net.ipv6.conf.vmbr0v605.disable_ipv6 = 0

VM is started and hostconfig on vlan 102 and 605 is gone

~# sysctl -qa 2>/dev/null  | grep 'disable_ipv6'
net.ipv6.conf.all.disable_ipv6 = 0
net.ipv6.conf.bond0.disable_ipv6 = 1
net.ipv6.conf.bond0/102.disable_ipv6 = 1
net.ipv6.conf.bond0/605.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 0
net.ipv6.conf.eth0.disable_ipv6 = 0
net.ipv6.conf.eth1.disable_ipv6 = 0
net.ipv6.conf.eth2.disable_ipv6 = 0
net.ipv6.conf.eth3.disable_ipv6 = 0
net.ipv6.conf.lo.disable_ipv6 = 0
net.ipv6.conf.tun0.disable_ipv6 = 0
net.ipv6.conf.vmbr0.disable_ipv6 = 0
net.ipv6.conf.vmbr0v102.disable_ipv6 = 1
net.ipv6.conf.vmbr0v605.disable_ipv6 = 1
