Anybody can help on linux_s3 (kvm autotest)?
When running the testcase linux_s3 to test kvm, we constantly got
'bash: echo: write error: Resource temporarily unavailable'.
This testcase can be found at
autotest/client/tests/kvm/tests/linux_s3.py
(or autotest/client/tests/kvm/kvm_tests.py in the
Hello,
If I suspend and resume a guest under kvm, or I migrate it from one
host to another, I sometimes get a soft lockup.
Is there a timer mode to prevent or reduce the likelihood of these?
Thanks

Subject: [PATCH] Support Pause Filter in AMD processors
New AMD processors (Family 0x10 models 8+) support the Pause
Filter Feature. This feature creates a new field
So far I've been using files and/or LVM partitions for my VMs --
basically by using virt-manager and modifying existing XML configs and
just copying my VM files to be reused.
I'm wondering how KVM storage pools work -- at first I thought it was
something like KVM's version of LVM where you can jus
(Applies to kvm.git/master:083e9e10)
For details, please read the patch headers.
[ Changelog:
v2:
*) We now re-use the vmfd as the binding token, instead of creating
a new separate namespace
*) Added support for switch_to(mm), which is much faster
*) Added
We want to use these functions from withing KVM, which may be built as
a module.

What: xinterface is a mechanism that allows kernel modules external to
the kvm.ko proper to interface with a running guest. It accomplishes
this by creating an abstracted interface which does not expose any
private details of the guest or its related KVM structures, and provides
a mechanism to fin
We want to add a more efficient way to get PIO signals out of the guest,
so we add an "xioevent" interface. This allows a client to register
for notifications when a specific MMIO/PIO address is touched by
the guest. This is an alternative interface to ioeventfd, which is
performance limited by i
This allows a scatter-gather approach to IO, which will be useful for
building high performance interfaces, like zero-copy and low-latency
copy (avoiding multiple calls to copy_to/from).
The interface is based on the existing scatterlist infrastructure. The
caller is expected to pass in a scatter

Much of so far vendor-specific code for setting up guest debug can
actually be handled by the generic code. This also fixes a minor deficit
in the SVM part /wrt processing KVM_GUESTDBG_ENABLE.

Give user space more flexibility /wrt its IOCTL order. So far updating
the rflags via KVM_SET_REGS ignored potentially set single-step flags.
Now they will be kept.
