Hi, Excuse me, I have watched qemu_driver.c where most of the libvirt API is overrided in order to connect qemu. But I am confused which functions then call those qemu_driver API? I mean where is the qemu_driver implementation? Libvirt.c? But how does the qemu_driver connect and control qemu? Thanks a lot! Regards, Corey ------...

Here is v11. Fixed comments/bugs and updated against the latest libvirt.git. Changes v10->v11: - fixed comments on each patches - fixed cgroup handling in patch 3. - fixed MODIFY_CURRENT handling in patch 4. most of diff comes from refactoring qemu/qemu_driver.c -- conf/domain_conf.c | 40 ++ conf/domain_conf.h | 5 libvirt_private.syms | 3 qemu/qemu_driver.c | 727 +++++++++++++++++++++++++++++++-------------------- 4 files changed, 500 insertions(+), 275 deletions(-) Thanks, -Kame

​Hello, I have been trying to track different phases of a live migration process. I am using libvirt ​with qemu-kvm. I am issuing migration commands using virsh. Now, I want to measure the time spent in each phase of live migration, e.g., pre-copy and stop-copy. I stumbled upon the file qemu_driver.c. It has functions like qemudDomainMigratePrepare2 qemudDomainMigratePerform qemudDomainMigrateFinish2 I want to know whether qemudDomainMigratePerform and qemudDomainMigrateFinish2 directly map to the pre-copy and stop-copy phase? or the qemudDomainMigratePerform function performs both of the...

Hello Everyone, My pc run in CentOS 7.4 and install libvirt-4.0.0 + Qemu-kvm 2.9.0 + Ceph 10.2.10 ALL-in-One. I use python-sdk with libvirt and run [self.domain.updateDeviceFlags(xml, libvirt.VIR_DOMAIN_AFFECT_LIVE)] on CDROM (I want to change media path). However, I enable libvirt debug log , the log as below: "2018-02-26 13:09:13.638+0000: 50524: debug :

...ich represents the input of virFindFileInPath in Util.c. Through virFindFileInPath, one could find a requested executable file in the PATH env to start specified hypervisors. So could you please tell me what the value of args[0] is? Or where does cmd->args initialize? 2. In qemu_driver.c, there is a function call "vm = virDomainFindByUUID(&driver->domains, dom->uuid);", whose returned value "vm" is important in the next functions. Then we could get the "vm"'s value in hash.c which is the end part to lookup domains saved in hashtable....

Libvirt Version: 0.9.8 Hi: I added a new api for qemu_driver. and both added libvirt.c and remote. I tested it and it worked well. the function of this new api was add a new field in xml config of domain. (I added it like qemudDomainSetMemoryFlags)at the same time, I added a new member to struct virDomainDef. then I tested xml config converted to virDomain...
