similar to: [PATCH supermin] Add support for a DAX root filesystem.

Various patches to make supermin quieter. By outputting fewer messages on the fast path, we use the slow emulated UART less, and this improves boot times. Also remove some kernel modules that we cannot or should not be using, which also improves boot times. Rich.

Require the root= parameter is passed to specify which root (apppliance) to mount. Libguestfs has done this since 2012. The other two patches are small code refactorings in the init program. Rich.

v2 -> v3: - Rebase on top of the other patches. Rich.

NOTE: not for upstream, yet. v1 -> v2: - Remove the dependency on enabling ACPI, since ACPI is now enabled all the time. Rich.

I could swear that I remember seeing some announcement somewhere that Zaptel now supported drop-and-insert across spans on a TE410P, but now I can't find it. Am I imagining this? We just got our TE410 up and running, and if we could cross-connect digital channels with it, I think we'd buy another one for the remote end (instead of using the T100P we have).

v1 -> v2: - If we split out the init program into a separate init/ directory, that makes it much easier to build against an alternate libc. I tried to build against uClibc, but uClibc requires an entire build chain, which looked like it was going to be a massive ballache. Rich.

Hi I am trying to run CoreOS (Container Linux) as a guest OS using KVM/QEMU. One of their suggestions is to pass config info into the VM using the "fw_cfg" option . When I try this I get the error "-fw_cfg invalid option". If I run the vm with the help option it does not list the fw_cfg option. However, according to the qemu documentation, see here

Document what each module does, using *.mli files. Remove the --dtb option, it's obsolete. Rename modules according to their purpose. Rich.

v1 -> v2: - I fixed the end condition of the loop in parse_root_uuid. - Retested. Didn't change the busy wait loop into a function or macro, as per discussion on IRC. Rich.

Hi For the latest seabios version, it said: Support for vga emulation over a serial port in SeaBIOS (sercon). So I want to know how can I find the application of this feature in libvirt? And whether my understanding is correct? There are no related instruction on the website: https://libvirt.org/ My understanding: (1) The feature means: we can set this the IO address of a serial port to

Allow an alternate libc, such as dietlibc, to be used for the init binary in the supermin appliance. Rich.
