similar to: [RFC/PATCH 12/15] kvm-s390: API documentation

This patch series introduces a backend for kvm to run on IBM System z machines that uses the mainframe's sie virtualization capability. This work runs 64bit guests on z800/z890/z900/z990/z9/z10 class machines with a 64bit linux host. Userspace will follow once we're done brushing it over. The patch queue consists of the following patches, which can be applied in sequence on top of kvm.git

From: Carsten Otte <cotte at de.ibm.com> From: Christian Borntraeger <borntraeger at de.ibm.com> This path introduces handling of sie intercepts in three flavors: Intercepts are either handled completely in-kernel by kvm_handle_sie_intercept(), or passed to userspace with corresponding data in struct kvm_run in case kvm_handle_sie_intercept() returns -ENOTSUPP.

From: Carsten Otte <cotte at de.ibm.com> This patch contains the s390 interrupt subsystem (similar to in kernel apic) including timer interrupts (similar to in-kernel-pit) and enabled wait (similar to in kernel hlt). In order to achieve that, this patch also introduces intercept handling for instruction intercepts, and it implements load control instructions. This patch introduces an

All, These days I am trying to understand the interaction relationship between the libvirt and KVM kernel module, eg. kvm_intel.ko. We know that KVM kernel module expose an entry in form of device file "/dev/kvm" which can be accessed by user space application to control, for example, create a VM using KVM_CREATE_VM with help of ioctl. Now let's say the tool virsh based upon

From: Martin Schwidefsky <schwidefsky at de.ibm.com> The SIE instruction on s390 uses the 2nd half of the page table page to virtualize the storage keys of a guest. This patch offers the s390_enable_sie function, which reorganizes the page tables of a single-threaded process to reserve space in the page table: s390_enable_sie makes sure that the process is single threaded and then uses

Hello, In my testing of crosvm[1] with Linux 4.4.175, I am observing failures on a 'kevin' Chromebook (RK3399) device - the guest kernel does not even get to the point of printing its first messages, and the host seems to be spinning at 100% CPU in KVM_RUN. I narrowed this down to the 4.4 stable backport of "arm64: KVM: Skip MMIO insn after emulation" - with this patch

Hello, I am trying to use virt-resize. It does not work. I set the debug environment variables and ran libguestfs-test-tool. The following is its output. I am running RHEL 6.5 desktop with kernel: Linux hustedm-lnx4 2.6.32-431.5.1.el6.x86_64 #1 SMP Fri Jan 10 14:46:43 EST 2014 x86_64 x86_64 x86_64 GNU/Linux Please let me know what I have missed. Thanks, Mark bash-4.1$

Hello Rich, Well, I did give that a try. But it is back to being unable to access kvm (log attached). It did make the qemu error go away.
