KVM Virtual CPU time profiling

Hi All, Is there a way in KVM to measure the real physical (CPU) time consumed by each running Virtual CPU? (I want to do time profiling of the virtual machines running on host system) Also, is there an explanation somewhere on how Virtual CPU scheduling is achieved in KVM? Thanks Abhishek

GDB + KVM Debug

Hi All, I see Qemu support GDB server that allows debugging kernels, boot loaders and others. Is this kind of support is available when KVM is enabled. For some reason the single stepping of instructions doesn't seem to work when KVM is in use. So what debug capabilities (for Guest SW) KVM

KVM and Qemu Synchronization

Hi All, I am interested to know how the KVM Synchronize with Qemu. I know KVM maintain the time in PIT/RTC and Qemu it's own thread for IO devices callback (using alarm timers).  How it is guaranteed that Qemu maintained view of time is not passing to slow or too fast w.r.t KVM VCPu. Also,
