Hi list! Problem solved... Still it FEELS like NetworkManager broke networking in the VMs, still not confirmed.
Solution: $ sudo su - # modprobe nbd max_part=63 # qemu-nbd -c /dev/nbd0 /tmp/qcowimag # install -d /mnt/centos # mount /dev/nbd0p1 /mnt/centos # chattr +i /mnt/centos/etc/sysconfig/network-scripts/ifcfg-eth0 # umount /mnt/centos # ... No, that's not nice!, but setting NM_CONTROLLED="no" didn't help. Hope this may help someone sometime. # kraM On 15:24 Mon 21 Oct, Mark Kusch wrote: > Hi list, > > feels like an issue with NetworkManager in CentOS (not confirmed yet). > ifcfg-eth0 has configured eth0 to be managed by > `NetworkManager' (NM_CONTROLLED="yes"). > > Current approach is to mount and modify the qcow image > and configure NM_CONTROLLED="no". > > Currently no success. > > # kraM > > > On 14:49 Mon 21 Oct, Mark Kusch wrote: > > Hi list, > > > > I've a vnet defining IP and MAC address fields (required). > > I've a working bridge configuration which should grant accecss to a > > corporate DHCP server configured for exactly these IP/MAC pairs. > > I've a CentOS qcow2 image with eth0 configuration set to DHCP. > > > > When instantiating a VM it comes up with eth0 configured with IP > > 0.192.222.10/24.
