[Qemu-devel] [PATCH 2/7] KVM: i386: Re-inject #DB to guest with updated DR6

From: Liran Alon If userspace (QEMU) debug guest, when #DB is raised in guest and intercepted by KVM, KVM forwards information on #DB to userspace instead of injecting #DB to guest. While doing so, KVM don't update vCPU DR6 but instead report the #DB DR6 value to userspace for further handling. S

[Qemu-devel] [PATCH 4/7] linux-headers: import improved definition of KVM_GET/SET_NESTED_STATE structs

This patch improves the KVM_GET/SET_NESTED_STATE structs by detailing the format of VMX nested state in a struct. The VMX nested state is accessible through struct kvm_vmx_nested_state though, to avoid changing the size of the structs, it has to be accessed as "vmx.data[0]" rather than just "vmx.d

From: Liran Alon Kernel commit 8fcc4b5923af ("kvm: nVMX: Introduce KVM_CAP_NESTED_STATE") introduced new IOCTLs to extract and restore KVM internal state used to run a VM that is in VMX operation. Utilize these IOCTLs to add support of migration of VMs which are running nested hypervisors. Revi

[Qemu-devel] [PATCH preliminary 0/7] target-i386/kvm: live migration support for nested VMX

This is mostly Liran's work. It's preliminary because he found some cases that break but he hasn't debugged them fully yet (a kernel bug is suspected though) and because my version, which only requires a very small and backwards-compatible linux-headers change (patch 4), has seen even less testing
