Hello

is it possible to set the kernel name a VE get for the "uname" call?  
There seams to be a bug in the oracle installer with long kernel names  
and we try to test if this is still the case for our oracle 11g client  
setup dying with segmentation fault inside the VE
Link to (possible) Oracle Bug :

Thanks

Andreas

See /proc/sys/kernel/virt_osrelease -- there you can see/set kernel 
version as visible from inside containers.

Hi all,

If I want to use veth for container networking,do I have to delete venet0?
If they can exist at the same time, which one is priorer to the other?How the packet goes before it get to the physical device?


Best Regards
Zhaohui Wang

no, they can co-exist

this depends upon you routing tables

host and ve communication [message #30723 is a reply to message #30696] Wed, 04 June 2008 23:12 Go to previous message

Hi all

I am tring to use unix domain socket to  do communication between the host and the container.

Now,it's working on the 2.6.18 stable kernel, if and only if I start the server socket inside the container and connect from the host, and with abstract name.

BUT,the same approach failed on 2.6.24 ovz004 kernel.

Can any one tell me what changes have been made to unix domain socket,and abstract namespaces. Does openvz separated socket namespace in ovz004?


Before I am digging the code,any information would be appreciated.




Thanks Den.


Best Regards
Zhaohui Wang
