When I changed the processor to Core2Duo it worked as expected (only CPU usage when needed). And I don't want to compile both libvirt and qemu-kvm from source since it is the production machine. The Proxmox team works very hard to make sure you are running the best software and getting stable updates and security enhancements, as well as quick support. 6.000+ satisfied customers have Source

If you disable ACPI, you can't do SMP. Comment 29 Matti Lehti 2010-12-15 16:02:40 EST I never saw had this problem with F13, but noticed it some time after upgrading to F14.

  1. My linux works good, never tried windows.Did.
  2. At what point is brevity no longer a virtue?
  3. The only solution I've found so far is to reinstall with ACPI enabled and make sure during install that the Multiprocessor HAL is selected.
  4. Nothing abnormal.A quick perf shows this:# ........ ........ ................................................................#4.96% qemu-kvm [kvm] [k] kvm_arch_vcpu_ioctl_run4.83% qemu-kvm [kvm_intel] [k] vmx_vcpu_run4.47% qemu-kvm [kernel.kallsyms] [k] find_busiest_group3.23% qemu-kvm [kernel.kallsyms] [k] _spin_lock3.10% qemu-kvm [kernel.kallsyms] [k] native_write_msr_safe1.24% qemu-kvm [kernel.kallsyms]
  5. When both machines are completely logged out, the Linux machine uses 1% CPU, the Windows one 45-50%, according to top.
  6. Is it bad practice to use GET method as login username/password for administrators?
  7. Maybe it is a similar situation here?
  8. KVM stands for Kernel-based Virtual Machine a full virtualization solution for Linux.

Create a VM with with 1 CPU, x86_64 architecture, 512MB RAM, set to PXE Boot (i.e. Stop. Check this links : http://support.microsoft.com/default.aspx?scid=kb;EN-US;919521 For me, this solved the problem, CPU usage is now normal. Windows 10 Virtio Drivers Would it be possible for you to test with the latest upstream git?

I have no OS on the configured disk, and if I let it go to attempt to boot and fail, the CPU load falls to zero. Actually uninstall the drivers and switch the disk/net models back to their defaults, or something else? He's a Linux System Engineer, Tech fanatic and an Open Source fan. However it's still controllable and could be shutdown by itself.

any idea? As you don't work in the same field I don't really expect you to understand these things, just as I wouldn't understand anything Oracle. –John Gardeniers Sep 18 '12 at 23:12 Please also show the working command line so we can compare (the 'core2duo' one mentioned in Comment #0). The kvm process is always taking something like 100%+ cpu even when the VM is idle...

Qemu Kvm High Cpu Usage

Comment 4 Cole Robinson 2013-08-31 10:58:14 EDT Hi Ferry, thanks for the quick response. https://ispire.me/windows-7820082012-causing-high-cpu-loads-on-kvm/ If I start a VM with 1 virtual CPU, the physical box goes to 50% overall utilization which is 100% of a core. Kvm Windows Guest High Cpu Subscribing... Qemu-kvm 100% Cpu According to the taskmgr any active process takes 99% CPU.

That bug lists physical CPU as running at 20% with an idle guest. Then kvm should refuse to try, surely? Kvm High Cpu Usage Idle

Zoltan Zoltan Frombach at Apr 7, 2013 at 5:41 pm ⇧ Yeah, I would not compile libvirt and qemu-kvm from source either.What about this:http://forum.proxmox.com/threads/5770-Windows-guest-high-context-switch-rate-when-idle?se028c4f45a28ea2c09a3f311b600e7d&p2972#post32972Did you try this? I'm using virt-manager to set it all up and run it.

Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version Does windows even correctly boot, or just start spinning at 100% soon after starting the VM? Feel free to just post the whole log file if you want, though it will help to specifically point out the working configuration.

Bug1000176 - Windows XP guest uses 100% guest CPU Summary: Windows XP guest uses 100% guest CPU Status: CLOSED WORKSFORME Aliases: None Product: Fedora Classification: Fedora Component: qemu (Show other bugs) If I start a VM with 1 virtual CPU, the physical box goes to > 50% overall utilization which is 100% of a core. Thank you for reporting this bug and we are sorry it could not be fixed. Check This Out Unfortunately, the problem still exists.

Thanks, I'll mark it invalid (meaning "can't reproduce it to get more information") for now, please do re-open if anyone can reproduce. It's not a Proxmox / KVM problem ! If I start a VM with 2 virtual CPUs, the physical box uses 100% on each core. Looking into it now.

As a result we are closing this bug. As time passes on the host the loadvm start to become very slow. Maybe there's something similar to VMware tools you should install in your VM? It works fine for Windows Vista using both cores.
