Hi, I have buit Xen (32 bit) with PAE and can start multiple Paraguests with 4 gig memory, but cannot launch a single VM with more than 4 gb memory. I would like to launch 1 VM with 30GB or so memory. Are there any config paramters like kernel,/inittrd that need to be changed. I have the ramdisk set to the initrd I used to boot xen with PAE. Thanks - padma

Hi, What is the behaviour of rsync on receiving SIGUSER1 signal? Can I block it in someway so that my application that repeatedly calls rsync and rsync itself will run smoothly. Regards, Preeti -------------- next part -------------- HTML attachment scrubbed and removed

...uys, I'm working a lot with Linux Containers(LXC) and find it extremely nice to have the ability to rsync files from the host machine to the container without the need of SSH. What I did was a simple patch, which added the new option --mount-ns-pid=PID and also added a call to setns() in the do_fork() function. The idea is, that rsync will use the PID to create a path (/proc/PID/ns/mnt), open that path and give the file descriptor to setns(), which in turn will switch to the new mount namespace and so, the file operations will be done in the new mount namespace instead of the host's own...

I filed this as bug 4150 http://rsync.samba.org/cgi-bin/rsync/ We had a few hundred hung processes and reached the limit for "max user processes" (see the ulimit command). rsync did not handle this very well. It passed -1 as a PID to kill(). When kill() gets -1, it kills all of the processes owned by that user, or if run by root, all processes. I attached a one line fix. Let me
