[libvirt] [PATCH v2] qemuProcessStart: Switch to flags instead of bunch booleans
by Michal Privoznik 17 Apr '12

17 Apr '12

Currently, we have 3 boolean arguments we have to pass to qemuProcessStart(). As libvirt grows it is harder and harder to remember them and their position. Therefore we should switch to flags instead. --- diff to v1: -fix a test for START_PAUSED flag src/qemu/qemu_driver.c | 45 +++++++++++++++++++++++++++++---------------- src/qemu/qemu_migration.c | 7 ++++--- src/qemu/qemu_process.c | 21 +++++++++++++-------- src/qemu/qemu_process.h | 12 ++++++++---- 4 files changed, 54 insertions(+), 31 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 65ed290..436ef37 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -1351,10 +1351,16 @@ static virDomainPtr qemudDomainCreate(virConnectPtr conn, const char *xml, virDomainPtr dom = NULL; virDomainEventPtr event = NULL; virDomainEventPtr event2 = NULL; + unsigned int start_flags = VIR_QEMU_PROCESS_START_COLD; virCheckFlags(VIR_DOMAIN_START_PAUSED | VIR_DOMAIN_START_AUTODESTROY, NULL); + if (flags & VIR_DOMAIN_START_PAUSED) + start_flags |= VIR_QEMU_PROCESS_START_PAUSED; + if (flags & VIR_DOMAIN_START_AUTODESTROY) + start_flags |= VIR_QEMU_PROCESS_START_AUTODESROY; + qemuDriverLock(driver); if (!(def = virDomainDefParseString(driver->caps, xml, QEMU_EXPECTED_VIRT_TYPES, @@ -1383,10 +1389,9 @@ static virDomainPtr qemudDomainCreate(virConnectPtr conn, const char *xml, if (qemuDomainObjBeginJobWithDriver(driver, vm, QEMU_JOB_MODIFY) < 0) goto cleanup; /* XXXX free the 'vm' we created ? */ - if (qemuProcessStart(conn, driver, vm, NULL, true, - (flags & VIR_DOMAIN_START_PAUSED) != 0, - (flags & VIR_DOMAIN_START_AUTODESTROY) != 0, - -1, NULL, NULL, VIR_NETDEV_VPORT_PROFILE_OP_CREATE) < 0) { + if (qemuProcessStart(conn, driver, vm, NULL, -1, NULL, NULL, + VIR_NETDEV_VPORT_PROFILE_OP_CREATE, + start_flags) < 0) { virDomainAuditStart(vm, "booted", false); if (qemuDomainObjEndJob(driver, vm) > 0) qemuDomainRemoveInactive(driver, vm); @@ -4138,9 +4143,9 @@ qemuDomainSaveImageStartVM(virConnectPtr conn, } /* Set the migration source and start it up. */ - ret = qemuProcessStart(conn, driver, vm, "stdio", false, true, - false, *fd, path, NULL, - VIR_NETDEV_VPORT_PROFILE_OP_RESTORE); + ret = qemuProcessStart(conn, driver, vm, "stdio", *fd, path, NULL, + VIR_NETDEV_VPORT_PROFILE_OP_RESTORE, + VIR_QEMU_PROCESS_START_PAUSED); if (intermediatefd != -1) { if (ret < 0) { @@ -4710,6 +4715,10 @@ qemuDomainObjStart(virConnectPtr conn, bool autodestroy = (flags & VIR_DOMAIN_START_AUTODESTROY) != 0; bool bypass_cache = (flags & VIR_DOMAIN_START_BYPASS_CACHE) != 0; bool force_boot = (flags & VIR_DOMAIN_START_FORCE_BOOT) != 0; + unsigned int start_flags = VIR_QEMU_PROCESS_START_COLD; + + start_flags |= start_paused ?

[libvirt] [libvirt-test-API PATCH 0/2] Documentation update
by Martin Kletzander 17 Apr '12

17 Apr '12

I updated part of the documentation that was changed in last few weeks. Screenshot test was updated again a little bit to suit the needs of a documentation and replaced the source codes of previous two tests mentioned in the documentation as it describe just what is needed and has no overhead on the reader. I'm not sure how the numbering goes in this case, but it can be updated later or I can send a v2 in case it needs to be fixed right away.

[libvirt] [PATCH] storage: lvm: use correct lv* command parameters
by Cole Robinson 16 Apr '12

16 Apr '12

lvcreate want's the parent pool's name, not the pool path lvchange and lvremove want lv specified as $vgname/$lvname This largely worked before because these commands strip off a starting /dev. But https://bugzilla.redhat.com/show_bug.cgi?id=714986 is from a user using a 'nested VG' that was having problems. I couldn't find any info on nested LVM and the reporter never responded, but I reproduced with XML that specified a valid source name, and set target path to a symlink.

16 Apr '12

Previous patches on numad made mistake with thinking numad will return CPUs list (numad document says CPUs list one place, and node list another place. :( Please see the patches' commit message for the details.

[libvirt] [test-API PATCH 0/3] make clean function optional
by Guannan Ren 16 Apr '12

The set of patches is to make the writing of clean function optional. If a testcase which doesn't dirty the testing environment, then the TESTCASE_clean function could be optional or omitted. Because loggers in python are static objects managed by the module itself. When you create one, it won't be removed until the shell quit. In test-API there are two loggers which are configured with two handlers for each. we need to find a way to destruct these two loggers in order no to affect other application. The idea is to clear the handlers of each logger in destructor of CaseLog and EnvLog. def __del__(self): self.logger.handlers = [] rename some unclear function and variables. for example: repos/domain/start.py domain -> mod start.py -> case start() -> func
