Host/guest clipboard?
Hi,
I''m trying to get copy/paste/cut working between my Xen host (FC8 64) and
guest OSs (Centos 5.1, Windows 2000). I''ve tried the viewer in virt-manager,
virt-viewer, and vncviewer. None of them seem to transfer clipboard contents
between host and guest, even with both clipboard checkboxes selected in
vncviewer options. Does anyone know how to get this working? Thanks.

TightVNC controlling a Mac OSX 10.4.9.
Need some pointers here. I've got CentOS 4.4, and I want to control my
OSX 10.4.9 box via VNC. It connects, and I get a little dot for the
mouse cursor, but just a black screen. I can see the mouse controlling
the OSX desktop...
Here's the output when I start in a terminal:
[d at f ~]$ vncviewer
VNC server supports protocol version 3.889 (viewer 3.3)

qemu-dm cpu utilization
Using an 8-way ES7000 with 32GB of ram, I''m running xen at changset 11217
with dom0_mem=3092M as a kernel parameter on a x86_64 hyperviser.
It appears that qemu is adding too much overhead to
virtual machines to display graphics.
If I boot a sles9sp3 domVT in runlevel 5 with vga=0x314 for a graphicalboot, and immediately use
vncviewer simply to watch the virtual machine as it boots,

qemu reverse vnc connection
I was looking at vnc.c to see what would be involved in making a reverse VNC connection (vnc server connects to the client), and it looks possible but I also wondered if there was any reason why libvncserver couldn''t be used instead? Both qemu-dm and libvncserver appear to be licensed under GPL although I haven''t checked what version.
I''ve never figured out whether

Unindent ERB output
Hi all,
I''d like to unindent a block of ERB specifically to combat the extra
spacing being added to content inside <textarea> by the browser. Is
there such a feature in ERB?
I shall denote indentation with underscores in the pseudo code example
below.
Thanks in advance,

tightvnc server fails to start
I tried to use tightvnc back in August and had some help, but I stopped
due to IPv6 support. Now I am back at tightvnc and cannot get the
server started. This is on a new Centos install that did have regular
vncserver working on it (I did a yum erase vnc-server first).
So I have a working /etc/sysconfig/vncserver and my user has the
appropriate ~/.vnc files that worked with regular vnc.

[PATCH v3] virtio_blk: unlock vblk->lock during kick
Holding the vblk->lock across kick causes poor scalability in SMP
guests. If one CPU is doing virtqueue kick and another CPU touches the
vblk->lock it will have to spin until virtqueue kick completes.
This patch reduces system% CPU utilization in SMP guests that are
running multithreaded I/O-bound workloads. The improvements are small
but show as iops and SMP are increased.

Xvnc from tightvnc crashing
Hi all,
I am having issues with running tightvnc-server on a CentOS 5.1 x86_64
machine (currently up-to-date, kernel 2.6.18-53.1.6.el5).
Occasionally, the Xvnc instance will just crash, taking with it
everything that I was running. When it crashes, it seems to do so
when I try to open some GUI program. So, for instance, I click on a
shortcut to open a program, and poof, it crashes. But it does

xenconsole: Could not read tty from store: No such file or directory
Hello Community,
I encountered an error while running "xm console domU". Here is the running
script:
# xm console domU
xenconsole: Could not read tty from store: No such file or directory
I googled and found out that this issue is mostly result from forgetting
starting xenconsole service.
However, after I started xenconsole, the issue is still there. Please see:

vncserver on IPv6
http://www.realvnc.com/products/enterprise/4.1/ipv6.html
IPv6 support in VNC Server E4.1.7/P4.1.2
VNC Server E4.1.7 & P4.1.2 are fully IPv6-aware, but is shipped with
IPv6 support disabled by default, for security reasons. IPv6 can be
enabled by setting "InTransports=IPv6,IPv4" (the default being IPv4
only), either on the command-line when starting vncserver under Unix
Ok.

Problem setting up VNC on SLES10 HVM DomU
I''ve just uneventfully installed SLES10 as an HVM DomU (after finding
out, the hard way, that OpenSUSE 10.3 won''t install on Intel VT).
This almost went without a hitch, but I''ve been banging my head against
a brick wall for a few hours trying to get VNC working. I can get a
remote desktop, but a few seconds after I log in to the remote desktop,

File size limit of 2Gb ish ?
Hi all,
I am running samba 3.0.14 on ubuntu breezy badger networked with another
ubuntu machine and my XP laptop.
File sharing is great except when a file exceeds 1.5 - 2 GB. The file transfer
fails after 1.5 - 2 GB with a file to large error. This seems to be a limit
for linux - windows and linux - linux which is a pain when trying to move

Missing fonts for tightvnc
You would think installing via yum would handle dependencies, but
perhaps fonts are not managed like dependencies.....
Anyway, I installed tightvnc to test out its IPv6 support.
Installed ok (after I erased regular vnc). But when I tried to start
it, I got 5 warnings about:
Font directory '/usr/X11R6/lib/X11/fonts/misc' not found - ignoring
