[Qemu-devel] [PATCH 01/16] virtio-scsi: Add wwpn and tgpt properties

From: Stefan Hajnoczi A vhost-scsi device must be bound to a tcm_vhost target port. This will be done by issuing an ioctl to the device with the wwpn and tgpt. This patch adds these properties to the virtio-scsi-pci device: qemu -device virtio-scsi-pci,wwpn=$TARGET_WWN,tgpt=$TPGT Future pat

[Qemu-devel] [PATCH 09/16] virtio-pci: support host notifiers in TCG mode

From: Stefan Hajnoczi Normally host notifiers are only used together with vhost-net in KVM mode. It is occassionally useful to use vhost with TCG mode, mainly for testing and development. This isn't hard to achieve, simply fall back to notifying the host notifier manually from qemu if KVM mode

From: Stefan Hajnoczi There is no longer a distinction between vlan clients and non-vlan clients in the net core. The net core only knows about point-to-point clients which are connected to a peer. It's time to rename the global list of net clients since it no longer refers to vlans at all. Si

From: Stefan Hajnoczi Another step in moving the vlan feature out of net core. Users only deal with NetClientState and therefore qemu_del_vlan_client() should be named qemu_del_net_client(). Signed-off-by: Stefan Hajnoczi Signed-off-by: Zhi Yong Wu --- hw/e1000.c |2 +- hw/eepr
