[Xen-devel] Accessing the VNC using HVM stub domain - xen 3.3.0
Hello all, I''m writing a documentation about the news features of xen 3.3.0. The VNC is available configured to access by domain 0 but I can''t access configuring it to work into -dm virtual machine. Below my conffiles: # /etc/xen/hvmachine kernel = "/usr/lib/xen/boot/hvmloader" builder=''hvm'' memory = 1024 name = "hvmachine" vcpus=2 vif = [ ''type=ioemu, bridge=eth0'' ] device_model = ''/usr/lib/xen/bin/stubdom-dm'' boot="cd" sdl=0 opengl=0 vnc=1 vnclisten="172.30.206.1" stdvga=0 # /etc/xen/hvmachine-dm kernel = "/usr/lib/xen/boot/ioemu-stubdom.gz" vif = [ ''ip=172.30.206.1'', ''bridge=eth0,mac=00:16:3e:21:a2:94'' ] disk = [ ''file:/home/iso/debian-LennyBeta2-amd64-CD-1.iso,hdc:cdrom,r'',''phy:/dev/empirevg/pvmachine,hda,w''] Any idea?

(apart from that your configuration files seem good) Samuel _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi Samuel, I believed that this IP was only to internal communication between the two virtual machines. I was mistaked. Thanks again!

Hi Samuel, Thans again,. Changing the subject, I''m impressed with the stub domain performance! I did some benchmarks using bonnie++ and netperf and it''s better than pure fullvirt machine. * netperf: stub-hvm: 25.99 Kbits/sec hvm: 15.23 Kbits/sec In bonnie++ benchmark, the item "write block" is impressive: ....................Per char........Block........Rewrite stub-hvm .....20898..........41857.......21045 hvm .............19046..........17462.......19331 These values are in K/sec.
