[libvirt] [PATCH] bhyve: cdrom support
by Roman Bogorodskiy 24 Jul '14

24 Jul '14

Add support for CDROM devices for bhyve driver using bhyve(8)'s 'ahci-cd' device type. As bhyve currently does not support media insertion at runtime, disallow to start a domain with an empty source path for cdrom devices. --- src/bhyve/bhyve_command.c | 43 +++++++++++++++++----- .../bhyvexml2argv-disk-cdrom.args | 3 ++ .../bhyvexml2argvdata/bhyvexml2argv-disk-cdrom.xml | 22 +++++++++++ tests/bhyvexml2argvtest.c | 1 + 4 files changed, 59 insertions(+), 10 deletions(-) create mode 100644 tests/bhyvexml2argvdata/bhyvexml2argv-disk-cdrom.args create mode 100644 tests/bhyvexml2argvdata/bhyvexml2argv-disk-cdrom.xml diff --git a/src/bhyve/bhyve_command.c b/src/bhyve/bhyve_command.c index f1862fe..7862bc8 100644 --- a/src/bhyve/bhyve_command.c +++ b/src/bhyve/bhyve_command.c @@ -152,13 +152,31 @@ bhyveBuildDiskArgStr(const virDomainDef *def ATTRIBUTE_UNUSED, virCommandPtr cmd) { const char *bus_type; + const char *disk_source; switch (disk->bus) { case VIR_DOMAIN_DISK_BUS_SATA: - bus_type = "ahci-hd"; + switch (disk->device) { + case VIR_DOMAIN_DISK_DEVICE_DISK: + bus_type = "ahci-hd"; + break; + case VIR_DOMAIN_DISK_DEVICE_CDROM: + bus_type = "ahci-cd"; + break; + default: + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("unsupported disk device")); + return -1; + } break; case VIR_DOMAIN_DISK_BUS_VIRTIO: - bus_type = "virtio-blk"; + if (disk->device == VIR_DOMAIN_DISK_DEVICE_DISK) { + bus_type = "virtio-blk"; + } else { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("unsupported disk device")); + return -1; + } break; default: virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", @@ -166,22 +184,26 @@ bhyveBuildDiskArgStr(const virDomainDef *def ATTRIBUTE_UNUSED, return -1; } - if (disk->device != VIR_DOMAIN_DISK_DEVICE_DISK) { - virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", - _("unsupported disk device")); - return -1; - } - if (virDomainDiskGetType(disk) != VIR_STORAGE_TYPE_FILE) { virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", _("unsupported disk type")); return -1; } + disk_source = virDomainDiskGetSource(disk); + + if ((disk->device == VIR_DOMAIN_DISK_DEVICE_CDROM) && + (disk_source == NULL)) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("cdrom device without source path " + "not supported")); + return -1; + } + virCommandAddArg(cmd, "-s"); virCommandAddArgFormat(cmd, "%d:0,%s,%s", disk->info.addr.pci.slot, bus_type, - virDomainDiskGetSource(disk)); + disk_source); return 0; } @@ -282,7 +304,8 @@ virBhyveProcessBuildLoadCmd(bhyveConnPtr driver ATTRIBUTE_UNUSED, disk = def->disks[0]; - if (disk->device != VIR_DOMAIN_DISK_DEVICE_DISK) { + if ((disk->device != VIR_DOMAIN_DISK_DEVICE_DISK) && + (disk->device != VIR_DOMAIN_DISK_DEVICE_CDROM)) { virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", _("unsupported disk device")); return NULL; diff --git a/tests/bhyvexml2argvdata/bhyvexml2argv-disk-cdrom.args b/tests/bhyvexml2argvdata/bhyvexml2argv-disk-cdrom.args new file mode 100644 index 0000000..eb38969 --- /dev/null +++ b/tests/bhyvexml2argvdata/bhyvexml2argv-disk-cdrom.args @@ -0,0 +1,3 @@ +/usr/sbin/bhyve -c 1 -m 214 -H -P -s 0:0,hostbridge \ +-s 3:0,virtio-net,faketapdev,mac=52:54:00:00:00:00 \ +-s 2:0,ahci-cd,/tmp/cdrom.iso bhyve diff --git a/tests/bhyvexml2argvdata/bhyvexml2argv-disk-cdrom.xml b/tests/bhyvexml2argvdata/bhyvexml2argv-disk-cdrom.xml new file mode 100644 index 0000000..d70219c --- /dev/null +++ b/tests/bhyvexml2argvdata/bhyvexml2argv-disk-cdrom.xml @@ -0,0 +1,22 @@ +<domain type='bhyve'> + <name>bhyve</name> + <uuid>df3be7e7-a104-11e3-aeb0-50e5492bd3dc</uuid> + <memory>219136</memory> + <vcpu>1</vcpu> + <os> + <type>hvm</type> + </os> + <devices> + <disk type='file' device='cdrom'> + <driver name='file' type='raw'/> + <source file='/tmp/cdrom.iso'/> + <target dev='hdc' bus='sata'/> + <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> + </disk> + <interface type='bridge'> + <model type='virtio'/> + <source bridge="virbr0"/> + <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> + </interface> + </devices> +</domain> diff --git a/tests/bhyvexml2argvtest.c b/tests/bhyvexml2argvtest.c index f6f2bc4..408c73a 100644 --- a/tests/bhyvexml2argvtest.c +++ b/tests/bhyvexml2argvtest.c @@ -104,6 +104,7 @@ mymain(void) DO_TEST("base"); DO_TEST("acpiapic"); + DO_TEST("disk-cdrom"); DO_TEST("disk-virtio"); DO_TEST("macaddr"); DO_TEST("serial"); -- 1.9.0

[libvirt] [PATCH] qemuConnectGetDomainCapabilities: Report error on unknown arch
by Michal Privoznik 24 Jul '14

24 Jul '14

If user hasn't provided any @emulatorbin, the qemuCaps are searched by @arch provided (which in fact can be guessed from the host). However, there's no guarantee that the qemu binary for @arch will exist. Therefore qemu capabilities may be nonexistent too. If that's the case, we should throw an error message prior jumping onto 'cleanup' label as the helper lookup function remains silent on no search result.

[libvirt] [PATCH RFC] storage: ZFS support
by Roman Bogorodskiy 24 Jul '14

24 Jul '14

Implement ZFS storage backend driver. Currently supported only on FreeBSD because of ZFS limitations on Linux. Features supported: - pool-start, pool-stop - pool-info - vol-list - vol-create / vol-delete Pool definition looks like that: <pool type='zfs'> <name>myzfspool</name> <source> <name>actualpoolname</name> </source> </pool> The 'actualpoolname' value is a name of the pool on the system, such as shown by 'zpool list' command. Target makes no sense here because volumes path is always /dev/zvol/$poolname/$volname. Users has to create a pool on his own, this driver doesn't support pool creation currently. A volume could be used with Qemu by adding an entry like this: <disk type='volume' device='disk'> <driver name='qemu' type='raw'/> <source pool='myzfspool' volume='vol5'/> <target dev='hdc' bus='ide'/> </disk> --- configure.ac | 43 +++++ include/libvirt/libvirt.h.in | 1 + po/POTFILES.in | 1 + src/Makefile.am | 8 + src/conf/storage_conf.c | 11 +- src/conf/storage_conf.h | 4 +- src/qemu/qemu_conf.c | 1 + src/storage/storage_backend.c | 6 + src/storage/storage_backend_zfs.c | 344 ++++++++++++++++++++++++++++++++++++++ src/storage/storage_backend_zfs.h | 29 ++++ src/storage/storage_driver.c | 1 + tools/virsh-pool.c | 3 + 12 files changed, 449 insertions(+), 3 deletions(-) create mode 100644 src/storage/storage_backend_zfs.c create mode 100644 src/storage/storage_backend_zfs.h diff --git a/configure.ac b/configure.ac index f37c716..7e46460 100644 --- a/configure.ac +++ b/configure.ac @@ -1734,6 +1734,10 @@ AC_ARG_WITH([storage-gluster], [AS_HELP_STRING([--with-storage-gluster], [with Gluster backend for the storage driver @<:@default=check@:>@])], [],[with_storage_gluster=check]) +AC_ARG_WITH([storage-zfs], + [AS_HELP_STRING([--with-storage-zfs], + [with ZFS backend for the storage driver @<:@default=check@:>@])], + [],[with_storage_zfs=check]) if test "$with_libvirtd" = "no";

[libvirt] [PATCH] change blkiotune weight range min from 100 to 10
by Martin Kletzander 24 Jul '14

24 Jul '14

This reflects the same change made in kernel commit df457f845e (before v2.6.38-rc7). On the rare occasion when the user would try setting the weight to value in range <10, 100) on older kernel, we will error out with EINVAL properly. Modifying the error message (adding a hint for example) would cause weird logs, especially without stacked error messages (I couldn't resist mentioning it again). There is no (easy) way of getting the limits from kernel, since it's not exposed.

[libvirt] [PATCH] spec: drop anything older than Fedora 13
by Eric Blake 24 Jul '14

24 Jul '14

RHEL 5 is based on libvirt 0.8.2, as was Fedora 13. RHEL 5 also happens to be the oldest box that we actively support with a buildbot, so it is time to clean up some crufty conditionals in the spec file that no longer are necessary for modern Fedora. Although it is probably okay to make further simplifications to a newer minimum Fedora version, that can be done as a later patch. This patch just focuses on cleaning any comparison of %{?fedora} that will always be true or false once we assume a minimum of F13. * libvirt.spec.in: Make with_audit default to on. Move other conditionals to a single RHEL-5 block. Simplify any fedora comparison older than 13. Document our assumptions.
