I just downloaded the latest version from jit with: git clone git://git.openvz.org/pub/linux-2.6.24-openvz linux-2.6.24-openvz.org (hope that is correct) configuration, compilation worked without problem (compiling for amd64). but when i try to start a VE I get the following error: any idea whats wrong? > vzctl start 101 sysfs: duplicate filename '0' can not be created WARNING: at fs/sysfs/dir.c:424 sysfs_add_one() Pid: 3251, comm: vzctl Tainted: GF 2.6.24 #1 Call Trace: [<ffffffff802ea26c>] sysfs_add_one+0x54/0xbd [<ffffffff802ea7a7>] create_dir+0x4f/0x87 [<ffffffff802ea961>] sysfs_create_dir+0x47/0x5c [<ffffffff8032474d>] kobject_get+0x12/0x17 [<ffffffff80324c7a>] kobject_add+0xf3/0x1a6 [<ffffffff80240c47>] user_kobject_create+0x77/0xa7 [<ffffffff80241090>] alloc_uid+0xe1/0x185 [<ffffffff802411b7>] copy_user_ns+0x71/0xde [<ffffffff8024ecf7>] create_new_namespaces+0x103/0x1da [<ffffffff8024efc1>] copy_namespaces+0x31/0x90 [<ffffffff883ea39d>] :vzmon:real_env_create+0x43c/0xd3e [<ffffffff883eaf22>] :vzmon:vzcalls_ioctl+0x283/0x498 [<ffffffff883e413d>] :vzdev:vzctl_ioctl+0x34/0x50 [<ffffffff802b0295>] do_ioctl+0x21/0x6b [<ffffffff802b052c>] vfs_ioctl+0x24d/0x266 [<ffffffff802b0581>] sys_ioctl+0x3c/0x5f [<ffffffff8020bf4e>] system_call+0x7e/0x83 kobject_add failed for 0 with -EEXIST, don't try to register things with the same name in the same directory.

I had the same problem but I see there is a bug report for that: http://bugzilla.openvz.org/show_bug.cgi?id=802 I did have the fair scheduler on and after disabling this: # zgrep CONFIG_FAIR /proc/config.gz # CONFIG_FAIR_GROUP_SCHED is not set it works. # uname -a Linux jmd1 2.6.24-openvz #1 SMP PREEMPT Sun Feb 10 23:42:00 EST 2008 x86_64 Dual Core AMD Opteron(tm) Processor 285 AuthenticAMD GNU/Linux # vzlist VEID NPROC STATUS IP_ADDR HOSTNAME 101 3 running 192.168.1.250 vs_pdc John
