From: Hongyong Zang <zanghongyong at huawei.com> Vhost-net uses its own vhost_memory, which results from user space (qemu) info, to translate GPA to HVA. Since kernel's kvm structure already maintains the address relationship in its member *kvm_memslots*, these patches use kernel's kvm_memslots directly without the need of initialization and maintenance of vhost_memory.

From: Amos Kong <akong at redhat.com> Currently virtio-net code relys on the layout of descriptor, this patchset removed the assumptions and introduced a control command to set mac address. Last patch is a trivial renaming. V2: check guest's iov_len V3: fix of migration compatibility make mac field in config space read-only when new feature is acked V4: add fix of descriptor layout

I'm having a bit of misbehavior wherein Dovecot seems to refuse to cooperate with my Mulberry MUA. By and large, everything works great. I can move mail back and forth happily. I can compose a note and copy the outgoing mail to my Dovecot "Sent" folder using my default Mulberry settings. But if I reply or forward a mail, I get a Mulberry error popup saying that it

This patch tries to implement an device IOTLB for vhost. This could be used with for co-operation with userspace(qemu) implementation of iommu for a secure DMA environment (DMAR) in guest. The idea is simple. When vhost meets an IOTLB miss, it will request the assistance of userspace to do the translation, this is done through: - Fill the translation request in a preset userspace address (This
