I have a bunch of Debian stretch machines with systemd where I find that tinc starts too early during boot, and fails to work. Typically it is running, but printing out Apr 14 00:53:41 db7 tinc[3077]: Can't write to Linux tun/tap device (tun mode) /dev/net/tun: Input/output error regularly. Unfortunately because it is running systemd does not restart it, even though it's not actually working. Restarting it manually fixes this. I just had another case where it didn't...

Here is an slightly updated version of the paravirt_ops patch. If your comments and criticism were welcome before, now it's even more! There are some issues that are _not_ addressed in this revision, and here are the causes: * split debugreg into multiple functions, suggested by Andi: - Me and jsfg agree that introducing more pvops (specially 14!) is not worthwhile. So, although we do

This is hopefully the last iteration of the pvops64 patch. >From the last version, we have only one change, which is include/asm-x86_64/processor.h: There were still one survivor in raw asm. Also, git screwed me up for some reason, and the 25th patch was missing the new files, paravirt.{c,h}. (although I do remember having git-add'ed it, but who knows...) Andrew, could you please push it

Hi folks, After some time away from it, and a big rebase as a consequence, here is the updated version of paravirt_ops for x86_64, heading to inclusion. Your criticism is of course, very welcome.

The following patches introduce the core infrastructure needed to paravirtualize the 32-bit x86 Linux kernel. This is done by moving virtualization sensitive insn's or code paths to a function table, paravirt_ops. This structure can be populated with hypervisor specific calls or native stubs and currently support running on bare metal, VMI, Xen, or Lhype. These patches apply to

This patch series implements the Linux Xen guest in terms of the paravirt-ops interface. The features in implemented this patch series are: * domU only * UP only (most code is SMP-safe, but there's no way to create a new vcpu) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes * xen console * virtual block
