DHCP failure

[narkisr]

I'm installing both Debian and Freebsd guests, both seems to fail to get an IP address (they do detect virtio0), my listed nics:

Iv set the bridge on re0

Thanks

I am unable to reproduce this. I have DHCP working on a host with a Realtec adapter.

Iv set the bridge on re0

How did you accomplish this? I don't see re0 as a member of bridge0 in your ifconfig output.

After running iohyve setup net=re0 my ifconfig output looks like this:

re0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
    options=82099<RXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC,LINKSTATE>

If you roll your own rc.conf instead of having iohyve take care of it, you might have an issue there.

If I ran the setup (again):

iohyve  setup net=re0                                                                   <<<
bridge0 is already enabled on this machine...

Following what you saw iv delete and recreated the bridge

$ ifconfig bridge0 destroy
$ sudo ./iohyve  setup net=re0
Seting up bridge0 on re0...
ifconfig: create: bad value
net.link.tap.up_on_open: 1 -> 1

Iv noticed the ifconfig: create: bad value, clearing tap0 solved this as well resulting in:

bridge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    ether 02:a9:30:b5:0d:00
    nd6 options=1<PERFORMNUD>
    id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 15
    maxage 20 holdcnt 6 proto rstp maxaddr 2000 timeout 1200
    root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0
    member: tap0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
            ifmaxaddr 0 port 4 priority 128 path cost 2000000
    member: re0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
            ifmaxaddr 0 port 1 priority 128 path cost 20000

Iv also disabled ipfw which seemed to cause an issue, now dhcp seems to be working but DNS doesn't :)

[narkisr]

Ok, ftp port was blocked now freebsd is installing!

I think that better docs (like what to look for after net setup) might help, also in the case of pc-bsd ipfw is enabled by default (I'm still not sure what rules to enable in order to make it work)

Thanks
