Due to parallel probing of the linux kernel `/dev/sd*` can't be used to
reliably address a hard disk. This can be seen by the many spurious
failures of the dracut CI, where `mdadm` failed with error 524 or tests
failed due to the success marker message written to the wrong disk.
* don't rely on `/dev/sd*` but use disk ids and `/dev/disk/by-id/ata-disk_<name>`
* specify the exact qemu machine architecture `-M q35` needed for the
disk ids. A later patch will move this to `run-qemu`, when all tests are converted
* due to `-M q35` the interface names have changed from
`ens2` -> `enp0s1` and `ens3` -> `enp0s2`
The network interfaces appear asynchronously and sometimes just too late,
after we're already halfway throught server-init.sh:
+ ip link set dev eth0 name ens3
Cannot find device "eth0"
+ ip addr add 192.168.50.1/24 dev ens3
Cannot find device "ens3"
+ dhcpd -cf /etc/dhcpd.conf -lf /var/lib/dhcpd/dhcpd.leases ens3 ens5
...
[ 8.040825] e1000 0000:00:03.0 eth0: (PCI:33MHz:32-bit) 52:54:01:12:34:56
[ 8.047105] e1000 0000:00:03.0 eth0: Intel(R) PRO/1000 Network Connection
...
No subnet declaration for ens3 (no IPv4 addresses).
** Ignoring requests on ens3. If this is not what
you want, please write a subnet declaration
in your dhcpd.conf file for the network segment
to which interface ens3 is attached. **
Whoopsie. Let's ensure all the interfaces are there before we proceed
fiddling around with them.
Debian based distros use dhcpd3 instead of just dhcpd. Accordingly
paths to lease files etc are different as well. This patch ensures
that the test-suite can run with either dhcpd or dhcpd3.
This patch enhances nfsroot and the nfs test-suite with compatibility
for debian based distros. This is mainly the difference of using
portmap instead of rpcbind and the missing file /etc/netconfig
This implements a default path of /tftpboot/%s if no path is provided,
and adds host name substitution for %s, with a fall back to the IP address,
as provided by the kernel's nfsroot handling.
The test suite is updated to test this functionality.
Test additional combinations of command line and DHCP option formats. This
is by no means the complete list, but gets us started with some common ones.
This creates a basic root filesystem, creates an initramfs, and tries
to boot to the basic filesystem.
The init code on the test filesystem prints how much memory is used vs. free
and then drops to a shell. Exiting the shell will power off the VM.
