Re: [Xen-users] git error
My fault,
it is not git but mercurial. Mercurial does not seem to have bisect
feature.
I'll try converting

Hi list,
I am hunting a bug between libvirt and xen, which seems to appeared
after xen-4.0.1rc3.
The problem is a "pipe leak". Each connection to libvirt leaves 3 open
files:
libvirtd 14758 root 18u unix
0xffff88002600ed00 351779 socket
libvirtd 14758 root 19r FIFO
0,8 351781 pipe
libvirtd 14758 root 20w FIFO
0,8 351781 pipe
Steps to reproduce:
1. install xen-4.0.1 and libvirt 0.7.6+
2. for i in `seq 1 1000`; do virsh -c xen://daman.vmin.cz list; done
if fails on "Too many open files"
After libvirt restart, works fine for cca 300 connections
I have not seen this with xen-3. Since libvirt links libxenstore:
libxenstore.so.3.0 => /usr/lib/libxenstore.so.3.0
(0x00007f8845fea000)
and since I have a box with xen-4.0.1rc3 which seems to work well, I
have tried to replace libxenstore.so.3.0 with one from older box.
Voila, no "pipe leak".
Now I would like to look into sources and try to find which change
introduced this behavior. Unfortunatelly,
I am unable to clone git repo:
los:/mnt/y# git clone http://xenbits.xen.org/xen-4.0-testing.hg

Does anyone have a fresh copy of xen repo? I'd like to try "git bisect".
