Comment # 15 on bug 1190501 from James Fehlig

Things seemed to have regressed with the new libguestfs

Errors during downloading metadata for repository 'fedora-cisco-openh264':
  - Curl error (6): Couldn't resolve host name for
https://mirrors.fedoraproject.org/metalink?repo=fedora-cisco-openh264-34&arch=x86_64
[Could not resolve host: mirrors.fedoraproject.org]

From the verbose output I see that eth0 in the appliance did not get an IP
addr. Also of interest from the output

+ iface=eth0
+ touch /etc/fstab
+ rm -f /etc/dhcp/dhclient-enter-hooks.d/resolved
+ dhclient --version
+ dhcpcd eth0
/init: line 126: dhcpcd: command not found

Hmm, why is it trying dhcpcd? dhclient should be available. From the host

# dhclient --version >/dev/null 2>&1
# echo $?
0

Not sure how the appliance is built, but appears it is missing the dhclient
binary (from dhcp-client package).
