Hi, I'm working on NetBSD support in pygrub: I've posted my work on the NetBSD port-xen list [1]. It adds support for FFSv2 to tools/libfsimage and NetBSD partition/disklabel support to tools/pygrub. I started off using xen-unstable and the xl tools on a kernel 3.2, but I'm now on xen-4.3 and kernel 3.10. Retrieving the kernel and arguments appears to work, but the boot process waits for a console escape character before continuing: dom0# pygrub --debug --output-directory=/tmp /dev/mapper/vg00-ffsv2 linux (kernel /tmp/boot_kernel.NR37Lm)(args "root=xbd0 ") dom0# md5sum /tmp/boot_kernel.NR37Lm 9e492b31e18f7e816f3e374d7f365857 /tmp/boot_kernel.NR37Lm dom0# $XEN/tools/xcutils/readnotes /tmp/boot_kernel.NR37Lm __xen_guest: GUEST_OS=NetBSD,GUEST_VER=4.99,XEN_VER=xen-3.0,LOADER=generic, VIRT_BASE=0xffffffff80000000,ELF_PADDR_OFFSET=0xffffffff80000000, VIRT_ENTRY=0xffffffff80100000,HYPERCALL_PAGE=0x00000101,BSD_SYMTAB=yes dom0# xl create -c ffsv2/config Parsing config from ffsv2/config #XXX here it hangs in a xenconsole until a Control-] is enterted ^] Daemon running with PID 3635 Copyright (c) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012 The NetBSD Foundation, Inc.

The boot continues with a new xenconsole after sending a control-]. I experimented with different boot arguments like "console=hvc0 xencons=tty" to no avail. I'm really clueless about what's wrong. Any help appreciated.
