Re: [libvirt] [PATCH 1/2] bhyve: add UTC clock support

Bhyve as of r279225 (FreeBSD -CURRENT) or r284894 (FreeBSD 10-STABLE) supports using UTC time offset via the '-u' argument to bhyve(8). By default it's still using localtime. Make the bhyve driver use UTC clock if it's requested by specifying <clock offset='utc'> in domain XML and if the bhyve(8) binary supports the '-u' flag. --- src/bhyve/bhyve_capabilities.c | 31 ++++++++++++++++++++++ src/bhyve/bhyve_capabilities.h | 5 ++++ src/bhyve/bhyve_command.c | 21 +++++++++++++++ src/bhyve/bhyve_driver.c | 13 +++++++++ src/bhyve/bhyve_driver.h | 2 ++ src/bhyve/bhyve_utils.h | 1 + .../bhyvexml2argvdata/bhyvexml2argv-acpiapic.args | 2 +- tests/bhyvexml2argvdata/bhyvexml2argv-base.args | 2 +- .../bhyvexml2argv-bhyveload-explicitargs.args | 2 +- tests/bhyvexml2argvdata/bhyvexml2argv-console.args | 2 +- .../bhyvexml2argv-custom-loader.args | 2 +- .../bhyvexml2argv-disk-cdrom-grub.args | 2 +- .../bhyvexml2argv-disk-cdrom.args | 2 +- .../bhyvexml2argv-disk-virtio.args | 2 +- .../bhyvexml2argv-grub-bootorder.args | 2 +- .../bhyvexml2argv-grub-bootorder2.args | 2 +- .../bhyvexml2argv-grub-defaults.args | 2 +- .../bhyvexml2argvdata/bhyvexml2argv-localtime.args | 3 +++ .../bhyvexml2argv-localtime.ldargs | 1 + .../bhyvexml2argvdata/bhyvexml2argv-localtime.xml | 23 ++++++++++++++++ tests/bhyvexml2argvdata/bhyvexml2argv-macaddr.args | 2 +- .../bhyvexml2argv-serial-grub-nocons.args | 2 +- .../bhyvexml2argv-serial-grub.args | 2 +- tests/bhyvexml2argvdata/bhyvexml2argv-serial.args | 2 +- tests/bhyvexml2argvtest.c | 2 ++ 25 files changed, 117 insertions(+), 15 deletions(-) create mode 100644 tests/bhyvexml2argvdata/bhyvexml2argv-localtime.args create mode 100644 tests/bhyvexml2argvdata/bhyvexml2argv-localtime.ldargs create mode 100644 tests/bhyvexml2argvdata/bhyvexml2argv-localtime.xml diff --git a/src/bhyve/bhyve_capabilities.c b/src/bhyve/bhyve_capabilities.c index 3a55879..9b21649 100644 --- a/src/bhyve/bhyve_capabilities.c +++ b/src/bhyve/bhyve_capabilities.c @@ -141,3 +141,34 @@ virBhyveProbeGrubCaps(virBhyveGrubCapsFlags *caps) VIR_FREE(binary); return ret; } + +int +virBhyveProbeCaps(virBhyveCapsFlags *caps)
