Yes. Both patches work fine, in my case for NexentaStor 3.0.2 xen image

I still have trouble with b134.  First time  DomU  loads well . SMF configuration phase.
Afterwards one more DHCP request is required to obtain IP

Distro: debian unstable
Xen version: 4.0.0-2

This is the config:
#HVM
#still no qemu-dm in debian

#kernel = "/usr/lib/xen-4.0/boot/hvmloader"
#builder = 'hvm'
#memory = 2048
#name = "webserver"
#vif = ['bridge=eth0']
#disk = ['tap:tapdisk:aio:/srv/xen/webserver.img,xvda,w','phy:/dev/cdrom,xvdb:cdrom,r']
#device-model = '/usr/lib/xen-4.0/bin/qemu-dm'
#vnc = 1
#boot = 'd'


#PV

name = "webserver"
memory = 2048
bootloader = "/usr/lib/xen-4.0/bin/pygrub"
vif = ['bridge=eth0']
disk = [ "tap:tapdisk:aio:/srv/xen/webserver.img,xvda,w" ]
vnc = 1

When I run xm create /srv/xen/profiles/webserver.cfg I get:
Using config file "/srv/xen/profiles/webserver.cfg".
Error: [Errno 2] No such file or directory: 'aio:/srv/xen/webserver.img'

I created the image with dd:
# dd if=/dev/zero of=/srv/xen/webserver.img oflag=direct bs=1M seek=4095 count=1
# dd if=/dev/zero of=/srv/xen/webserver.img oflag=direct bs=1M count=4096

blktap2 works in current xen-testing-4.x and xen-unstable, but you should be use tap2:tapdisk:aio:...... (I do not know why it is not displayed in the documentation, but the code works the way). 

My configuration: "Opensolaris + pygrub + VHD" work fine for me.

Thanks.
