This is when trying to run Fedora Core 5 when setting a hostname and nameserver. When I didn't have the hostname and nameserver defined, it worked just fine.

vzctl create 1401 --ostemplate fedora-core-5-i386-minimal --ipadd 172.16.4.1

Works just fine:

root@elyssa:~# vzctl start 1401
Starting VPS ...
VPS is mounted
Adding IP address(es): 172.16.4.1
arpsend: 172.16.4.1 is detected on another computer : 00:07:84:46:74:0a
vps-net_add WARNING: arpsend -c 1 -w 1 -D  -e 172.16.4.1 eth0 FAILED
Setting CPU units: 1000
VPS start in progress...

vzctl set 1401 --save --hostname something.somewhere.com --nameserver 172.16.4.254

vzctl stop 1401

This doesn't work:

root@elyssa:~# vzctl start 1401

can you strace vzctl as:
# strace -f -o out vzctl start ...
please?

then press ctrl-c and check that no processes are stopped. otherwise send them a SIGCONT signal.

Attached is the out.gz file.

root@elyssa:~# strace -f -o out vzctl start 1401
Starting VPS ...
vzquota : (warning) Quota is running for id 1401 already
VPS is mounted
Adding IP address(es): 172.16.4.1
arpsend: 172.16.4.1 is detected on another computer : 00:07:84:46:74:0a
vps-net_add WARNING: arpsend -c 1 -w 1 -D  -e 172.16.4.1 eth0 FAILED

It just stops there. Pressing CTRL-C does nothing. It just sits there like it's doing something, but it's not doing anything.

If I press CTRL-Z, I get the expected

[1]+  Stopped                 strace -f -o out vzctl start 1401

If I

fg %1

, it goes back to its "just sitting there" state.

If I

bg %1

, it just sits there, but in the background instead.

If while it is in the background and I try

vzctl enter 1401

, I get

enter failed

.

I can't kill the strace process, except for

kill -9 2140

(2140 being the PID, of course)

If after -9'ing the process, I can do this (and get the following response):

root@elyssa:~# vzctl enter 1401
entered into VPS 1401
bash-3.1# exit
logout
exited from VPS 1401

[1]+  Killed                  strace -f -o out vzctl start 1401

If while entered in the VPS, I get this when I type:

bash-3.1# ifconfig
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0

          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

. As you can see, there is no venet0 for the 172.16.4.1 IP address like usual. I was expecting to get something more like this (from a VPS running FC4 instead of FC5):

bash-3.00# ifconfig
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0

I notice in the FC5 VPS, there is no /etc/resolv.conf file. But in my FC4 VPS, there is.

In the FC5 VPS:

bash-3.1# ll /etc/hosts*
-rw-r--r-- 1 root root  42 Mar 29 06:45 /etc/hosts
-rw-r--r-- 1 root root  42 Mar 29 06:45 /etc/hosts.31561
-rw-r--r-- 1 root root 161 Jan 13  2000 /etc/hosts.allow
-rw-r--r-- 1 root root 347 Jan 13  2000 /etc/hosts.deny

What is this hosts.31561? Is that a temp file from a process that isn't running/working properly, maybe? FC4 doesn't have it.

Diskspace:

bash-3.1# df -h
Filesystem            Size  Used Avail Use% Mounted on
simfs                 1.0G  135M  890M  14% /

I get the same. Is everyone getting this?

Same for me....
workaround:
replace

/bin/cp -fp ${file} ${file}.$$ || error "Can't copy file $file" $VZ_FS_NO_DISK_SPACE

with

/bin/cp -f ${file} ${file}.$$ || error "Can't copy file $file" $VZ_FS_NO_DISK_SPACE

and

/bin/cp -fp ${file} ${file}.$$ || error "Can't copy file $file" $VZ_FS_NO_DISK_SPACE

with

/bin/cp -f ${file} ${file}.$$ || error "Can't copy file $file" $VZ_FS_NO_DISK_SPACE

in put_param() resp. put_param2() in /etc/sysconfig/vz-scripts/dists/scripts/functions. This will touch /etc/hosts and /etc/sysconfig/network each time you start the VPS and modify the access time (filesystem inside the VPS); I can live with that Wink

Looks like there is something fishy with the cooperation of the /bin/cp from FC5 and OpenVZ framework.
