This patch allows the user to fault in pages on a virtual cpus address space for user controlled virtual machines.

[PATCH] virt-test: Add a class NumaNode v2

From: Amos Kong Dynamically checking hardware, use a dict to record the pin status, pin process to single cpu by 'taskset' command. Guest memory pining is already implemented in framework. process pining needs to be done in the testcases. Example: | numa_node = -1 # last node | p = virt_utils

[PATCH V2] kvm: make vcpu life cycle separated from kvm instance

From: Liu Ping Fan Currently, vcpu can be destructed only when kvm instance destroyed. Change this to vcpu's destruction taken when its refcnt is zero, and then vcpu MUST and CAN be destroyed before kvm's destroy. Signed-off-by: Liu Ping Fan --- arch/x86/kvm/i8254.c | 10 -- arch/x86

[PATCH V2 00/23] kvm tools: Prepare kvmtool for another architecture

Hi, This patch series rearranges and tidies various parts of kvmtool to pave the way for the addition of support for another architecture -- SPAPR PPC64. A second patch series will follow to present the PPC64 support. Building on the separation of x86-specific code into tools/kvm/x86, this seri

kvmtool's types.h includes , which by default on PPC64 brings in int-l64.h; define __SANE_USERSPACE_TYPES__ to get LL64 types. This patch also adds CFLAGS to the final link, so that any -m64 is obeyed when linking, too. Signed-off-by: Matt Evans --- tools/kvm/Makefile |2 +- to

[PATCH V2 05/23] kvm tools: Add arch-specific KVM_RUN exit handling via kvm_cpu__handle_exit()

[PATCH V2 06/23] kvm tools: Don't die if KVM_CAP_NR_VCPUS isn't available

[PATCH V2 07/23] kvm tools: Fix KVM_RUN exit code check

[PATCH V2 08/23] kvm tools: Add kvm__arch_periodic_poll()

Currently, the SIGALRM handler calls device poll functions (for serial, virtio console) directly. Which devices are present and which require polling is a system-specific decision, so create a new function called from common code & move the x86-specific poll calls into it. Signed-off-by: Matt Eva

[PATCH V2 09/23] kvm tools: Move arch-specific cmdline init into kvm__arch_set_cmdline()

Different systems will want different base kernel commandlines, e.g. non-x86 systems probably don't need noapic, i8042.* etc., so set the commandline up in arch-specific code. Then, if the resulting commandline is empty, don't strcat a space onto the front. Signed-off-by: Matt Evans --- tools/k

[PATCH V2 10/23] kvm tools: Add CONSOLE_HV term type and allow it to be selected

[PATCH V2 11/23] kvm tools: Fix term_getc(), term_getc_iov() endian bugs

term_getc()'s int c has one byte written into it (at its lowest address) by read_in_full(). This is expected to be the least significant byte, but that isn't the case on BE! Use correct type, unsigned char. A similar issue exists in term_getc_iov(), which needs to write a char to the iov rather

[PATCH V2 13/23] kvm tools: Allow load_flat_binary() to load an initrd alongside

This patch passes the initrd fd and commandline to load_flat_binary(), which may be used to load both the kernel & an initrd (stashing or inserting the commandline as appropriate) in the same way that load_bzimage() does. This is especially useful when load_bzimage() is unused for a particular arc

[PATCH V2 15/23] kvm tools: Perform CPU and firmware setup after devices are added

Currently some devices (in this case kbd, fb, vesa) are initialised after CPU/firmware setup. On some platforms (e.g. PPC) kvm__arch_setup_firmware() may be making a device tree. Any devices added after this point will be missed! Tiny refactor of builtin-run.c, moving timer start, firmware setup
