I have a system setup with minimal Centos7 install that holds two network cards. one is em1 and the other is em2
Alone the script seems have a hard time with em1 and em2. I had to trick the script by changing the eth0 to em1 in the script so that it could continue and install cloudmin. regardless of this I got a couple of problems that came up
one was something regarding the digest MD5 when cloudmin booted up, which I believe I fixed by doing 'yum install perl-Digest-MD5' following this fix https://github.com/webmin/webmin/issues/942#issuecomment-405896572
Then after doing a refresh status fully. I got another error about fuser which I do not recall the full error. either way after doing refresh status fully I finally got into the following error
"This system cannot be a KVM host : No bridge interfaces like br0 were found Virtual systems cannot be created or added until this is fixed."
It has been a nightmare trying to get two cards to work. I tried bonding them together, hoping I could simple bridge the bond and away I go. It does not seem that simple. I have tried just using one NIC and add it to the bridge from webmin->networking->network configuration->network interfaces but this seemed impossible as well, mostly because I'm doing it remotely since my server has no gui of course.
I had to manually go to the box, configure /etc/sysconfig/network-scripts/ifcfg-em1 NIC with: DEVICE=em1 TYPE=Ethernet BOOTPROTO=none ONBOOT=yes NM_CONTROLLED=no BRIDGE=br0
Then create /etc/sysconfig/network-scripts/br0: DEVICE="br0" BOOTPROTO="dhcp" ONBOOT="yes" TYPE="Bridge" STP=on DELAY=0 NM_CONTROLLED="no"
I thought I had done this before on a centos7 so I did not understand why I've such a hard time. When I checked my old box it was centos6.9 and not 7. And furthermore this box actually had eth* cards so cloudmind script took care of it all.
A couple of questions: Does cloudmin still have issues with centos7, or is this a script problem not picking up the em1 and em2 cards?
Not being all that familiar with bridging yet, can I make both em1 and em2 go on the bridge or is this just a one nic per bridge thing?
Wouldn't bonding both my NIC's then creating a bridge with that bond be a good idea? I fiddle with this enough to drive myself mad...
