Hello,

I'm trying to set up virtualizor on Hetzner. I have done this previously without any problems. Now I keep getting the warning when logging to virtualizor panel:

Quote
The viifbr0 is not started. Please run service virtnetwork start


My ifcfg-eth0

Code
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
HWADDR=d4:3d:7e:f8:ec:09
IPADDR=xxx.xxx.14.241
NETMASK=255.255.255.255
SCOPE="peer xxx.xxx.14.225"
GATEWAY=xxx.xxx.14.225
#IPV6INIT=yes
#IPV6ADDR=2a01:4f8:201:73f0::2/64
#IPV6_DEFAULTGW=fe80::1
#IPV6_DEFAULTDEV=eth0



My route-eth0

Code
ADDRESS0=0.0.0.0
NETMASK0=0.0.0.0
GATEWAY0=xxx.xxx.14.225



which is "identical" to my other servers that run virtualizor without any problem.

I open a ticker on virtualizor (#829018) and after 3-4 hours I got the reply:

Quote
Sir i have found that the netmask of the server is 255.255.255.255 you have to change it 255.255.255.0 as the 255 in the dose not allows to create the bridge .
Please ask dc to set some other network mask .

Please done please run service virtnetwork start from cli to start the bridge.


In a strange way the VPS that I created on this server are functioning without any problem.

My server runs Centos 6.5 x64.

Why is this happening? Have Hetzner changed something that makes it imposimple for virtualizor / KVM to work on netmask 255 or is it just lack of knowldge on behalf of Virtualizor techicians or something else?
Will Hetzner be able to change the Netmask only for my server or will they just laugh while reading my ticket to them?

Anyone else had that issue and got it solved? How?

Thank you in advance.

Best regards,
Spyros

Hello siddhesh,

OK, changed in ifcfg-eth0 to 255.255.255.0

Code
[root@d04 ~]# /etc/init.d/network restart

Update:

Hetzner has replied as below:

Quote
the netmask of IP xxx.xxx.14.241 is /27 so you can change the value to 255.255.255.224


I put 255.255.255.224 on the ifcfg-eth0 as NETMASK.
Do I have to change this on the IP POOL settings of Virtualizor?

I tried service virtnetwork start but the warning is still there.

it seems that setting NETMASK to the one provided by the Hetzner robot (when you hover the main server IP) and setting netmask to 255.255.255.0 to the Virtualizor IP pool Netmask did the trick.

Resolved.

I just had this problem and accidently resolved it. Very similar solution to this post with one change I think. I had to remove the GATEWAY from the ifcfg-eth0.

Here is what my files look like. Hope it helps someone.

my /etc/sysconfig/network-scripts/ifcfg-eth0 (changed the netmask and originally added the gateway)
Code

DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
HWADDR=xx:xx:xx:9f:63:86
IPADDR=xx.xx.29.239
#GATEWAY=xxx.xx.29.225
NETMASK=255.255.255.224
SCOPE="peer xxx.xx.29.225"
IPV6INIT=yes
IPV6ADDR=xxxx:xxx:xxx:20ee::2/64
IPV6_DEFAULTGW=fe80::1
IPV6_DEFAULTDEV=eth0


And my route-eth0 (made no changes to this file)
Code

# routing for eth0
ADDRESS0=0.0.0.0
NETMASK0=0.0.0.0
GATEWAY0=xxx.xx.29.225


And my virtualizor ip pool NETMASK is set to 255.255.255.0 as per the previous solution.

Side note.  I contacted Hetzner and got this response.

@Landon Have you managed to set up IPv6 with Hetzner and Virtualizor?
Virtualizor's techs have tried and failed so far.
Hetzner is not helpful at all (as always) in matters like these.

Spyros

Hi ,

Basically there are three issue that always occur on hetzner server when virtualizor tries to create bridge :-

1)It cannot create a bridge due to missing Gateway .
You have to add GATEWAY= .
You can get the gateway from SCOPE=

2)If the network mask is 255.255.255.255 it will fail to create a bridge .
You have to change netmask to any other netmask then 255.255.255.255

3)You have to check 4.2.2.1 is pingable .We check that ip is pingable after the bridge is created .
You can change the pingable ip settings from configuration option from admin panel if 4.2.2.1 is not pingable and add any other ip which is pingable from your server .
