Hi Alex/Scott,
Below is my understanding about the ONE_REG interface requirement for timer
registers.
Define the below 2 ONE_REG interface for TSR access:
KVM_REG_SET_TSR, // Set the specified bits in TSR
KVM_REG_CLEAR_TSR, // Clear the specified bits in TSR
QEMU will use the a

SMEP is disabled if CPU is in non-paging mode in hardware.
However KVM always uses paging mode to emulate guest non-paging
mode with TDP. To emulate this behavior, SMEP needs to be manually
disabled when
Hello all:
I have a CentOS server using KVM to host guest servers.
I am trying to limit the bandwidth usable by a guest server.
I tried to use tc, but that is only limiting the download bandwidth
to a server. It does not seem to filter packets uploaded by the
server.
Is there a tool to limit up

Since this presumably is constant for any given platform, wouldn't
a capability be more appropriate?
