Firewall prevents networking in VMs
Last modified: 2014-06-10 13:15:15 EDT
Installed a fresh F19.
Attempted to make use of VMs that I had used on a different system.
VMs couldn't start networking, they were stuck in "connecting"
I didn't think of the defaul firewall as a potential cause.
Once I did, the only obvious remedy was: disable firewall
(a) Could firewalld allow communication with local VMs by default?
(b) If (a) => no, then:
Could there be an easily discoverable fix to allow the user
to allow such communication, without having to disable the firewall?
What kind of VMs have you been using? Created and set up by libvirt?
Yes, all of them had been created using virt-manager. Linux VMs, RHEL/Fedora.
Are there errors in the logs related to libvirt or firewalld?
Is the libvirt configuration modified?
Please attach the output of the iptables-save command.
Looks I didn't have the time to follow up with the requested details :(
