Zitat von "Aleksey Ilyushin" <[EMAIL PROTECTED]>:
I tried to reproduce the problem with a
similar setup: XP guest via
Linux host (with MTU 1492) to OS X machine with Windows shares.
Writing to the Windows shared folders produces packets of 1506 bytes,
so everything works as it should. Could you restore back the smaller
MTU on your Linux host and try 'ping -f -l 1472
<ip_addr_of_win_share_machine>' from W2K guest? You should get
something like this:
Pinging 10.88.1.2 with 1472 bytes of data:
Reply from 192.168.100.100: Packet needs to be fragmented but DF set.
Packet needs to be fragmented but DF set.
Packet needs to be fragmented but DF set.
Packet needs to be fragmented but DF set.
Hmm, it were test like this that brought me on the MTU track. ;-)
Tried it again:
Set MTU to 1492 on all interfaces on the Linux host.
Abbreviated ifconfig output:
br0 Link encap:Ethernet HWaddr 00:16:17:f0:d8:44
inet addr:192.168.1.32 Bcast:192.168.1.255
Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1492 Metric:1
eth1 Link encap:Ethernet HWaddr 00:16:17:f0:d8:44
UP BROADCAST RUNNING MULTICAST MTU:1492 Metric:1
vbox1 Link encap:Ethernet HWaddr 00:ff:37:a2:fb:04
UP BROADCAST RUNNING MULTICAST MTU:1492 Metric:1
eth1: real interface, br0: brigde, vbox1: VBox HostInterface
ping -f -l 1472 works with the Linux host itself, but with none other
hosts on my network. No replies there, only timeouts. ifconfig vbox1
reports some dropped Tx packets.
When I set every MTU to 1500, I get the ping output about "fragmented
packets" with larger ping block sizes.
If there are no replies at all then, most
probably, your Linux host
acts as a "black hole" router which prevents proper path MTU discovery.
So it looks like. Any ideas how to tell my Linux not to do that ??

Okay. Filed a bug report here: http://www.virtualbox.org/ticket/1984 .
It has an example log and my kernel config. For now, I'm downgrading to
1.6.2 and seeing if that works again.
Also, /usr/src/linux symlink points to the correct headers. So not sure
on the problem here.
Thanks in advance

I am trying to get my guests (all of which
have this problem) to clock
properly. Like said in the forum post, the clock runs slow in the VM; 2
real seconds is a VM's second. I am however able to start a VM without
an issue. The fade-ins of the BIOS and Windows splash are very slow.
I've recompiled the vboxdrv kernel module several times and
re-modprobed. Older versions (even 1.6.2) worked. 1.6.4 was in the
updates, so I installed. I am considering downgrading to see if that
works.
This really sounds like your vboxdrv kernel module is not compiled
against
the correct kernel headers.
Thanks for your help. Should I file a bug
report?
Yes, please.
Kind regards,

So you are another candidate for whom the WinXP shared folders don't
work with the 1.6.4 additions. We are trying hard to debug this issue
but are currently not able to reproduce it. Please could you have a
look at
http://www.virtualbox.org/ticket/1915
You might follow the comments of pentagonik, that is, check if everything
was installed correctly. If all this doesn't help, try to reinstall the
1.6.4 additions.
I've uninstalled/installed the guest additions coming with 1.6.4
several times, so that didn't solve the problem, :(.
Do you have any special software installed in the guest? Virus scanners,
registry monitors or something like that? What localization of Windows is
that, French?
Yeap, the guest runs symantec antivirus. The XP is an EN-US version,
and the locale is EN-US with time zone for Costa Rica (Central
America)... I'm running under a firewall, but that doesn't seem to be
a problem for the bridged network interface... This XP comes with
lots of OS patches though, it's a company built OS around XP, with
several patches which don't show up under "installed software"
(actually the SP* patches don't show up there, but for sure it's
beyons SP2), so for there's special software and registry
configuration around, but I have NO clue what to look for (neither I'm
very XP acknowledgeable to go look for unfamiliar registry for
example), :(.
Kind regards,
Frank

Thanks a lot,
I have tried to install virtualbox and it always fails. The problem
arises when it tries to install msttcorefonts. A list of perhaps a
dozen or more failures to resolve a url messages are displayed. Other
than this, all appears well.
I'm able to create a vm, but when I try to start it so I can install
the guest (XP) OS, it fails and reports the missing msttcorefonts.
I've tried to find solutions on the web, but all I've found eventually
crash and burn because they run into the same msttcorefonts problem.
Is there a solution for this?
My OS is Ubuntu 8.04 and I've been trying to install
virtualbox_1.6.4-33808.

Our packages don't have a direct reference to msttcorefonts. But
ok, there is a dependency from libqt3-mt to fontconfig which has a
dependency to fontconfig-config which has a dependency to either
ttf-dejavu or ttf-bitstream-vera or ttf-freefont or gsfonts-x11 or
msttcorefonts.
So libqt-mt just needs a proper proportional font and you can install
ttf-bitstream-vera as well. Nevertheless the msttcorefonts package is
recommended since it provides all regular Microsoft TrueType fonts
for Linux. For doing this it downloads the fonts directly from the
internet. If that fails, you either have to check your internet
connection or the server could be temporarily down and you should try
to download the fonts with
dpkg-reconfigure msttcorefonts
Kind regards,
Frank
