[libvirt] [PATCHv6 5/6] bhyve: Add console support for grub-bhyve bootloader

This enables booting interactive GRUB menus (e.g. install CDs) with libvirt-bhyve. Caveat: A terminal other than the '--console' option to 'virsh start' (e.g. 'cu -l /dev/nmdm0B -s 115200') must be used to connect to grub-bhyve because the bhyve loader path is synchronous and must occur before the VM actually starts. Changing the bhyveProcessStart logic around to accommodate '--console' for interactive loader use seems like a significant project and probably not worth it, if UEFI/BIOS support for bhyve is "coming soon." --- src/bhyve/bhyve_command.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/src/bhyve/bhyve_command.c b/src/bhyve/bhyve_command.c index 203495c..12eaf71 100644 --- a/src/bhyve/bhyve_command.c +++ b/src/bhyve/bhyve_command.c @@ -447,6 +447,21 @@ virBhyveProcessBuildGrubbhyveCmd(virDomainDefPtr def, virCommandAddArgFormat(cmd, "%llu", VIR_DIV_UP(def->mem.max_balloon, 1024)); + if (def->nserials > 0) { + virDomainChrDefPtr chr; + + chr = def->serials[0]; + + if (chr->source.type != VIR_DOMAIN_CHR_TYPE_NMDM) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("only nmdm console types are supported")); + return NULL; + } + + virCommandAddArg(cmd, "--cons-dev"); + virCommandAddArg(cmd, chr->source.data.file.path); + } + /* VM name */ virCommandAddArg(cmd, def->name); -- 1.9.3
