Red Hat Bugzilla – Bug 806235
Unmatched the cpu usage from virt-manager to task manager in the guest.
Last modified: 2012-09-11 21:35:18 EDT
Description of problem:
In the guest, the cpu usage is 100% from task manager, but it's around 29% from virt-manager.
It's better to return "no respons" when the guest cpu usage reached 100% but not stay at 29%, or it will be confused for users.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. boot up a guest, xp-i386
2. open the IE browser, or issue other programme to occupy 100% cpu
3. track the cpu usage from task manager
unmatched cpu usage from the tools to the guest task manager.
Presents the true state of guest.
What CPU usage column, Guest CPU or Host CPU? How many VCPUS does the VM have?
Closing as INSUFFICIENT_DATA
Sorry for the late responds.
I have 4 physical cpu in host and 1 virtual cpu in guest, make the cpu usage to 100% in guest then get the 25% cpu usage in "performance -- CPU usage" of "show virtual hardware details", I know that it shows the usage per the whole physical cpus in host.
But I think it should be different in "Connection Details -- Overview", because I get the cpu usage in "show virtual hardware details" against the single vm but not connection.
I believe this is behavior by design, so I'm closing as NOTABUG.
