I have a KVM Host with 4 vms running 24/7h. All VMs runs smoothly but at a given time, all 4 VMs stops to ping and after 10 minutes, it continues to run.

I knew that they are not pinging because I have a script that pings them on every 10 minutes in order to warn if they are ok. I don't know if it's just a network problem or if the KVM simply stops to work.

How can I trace or log their current activity using libvirtd/virsh tools in order to find where the bottleneck is?

Watch the CPU/Network graph on GUI console is not an option because the problem occurs between 6 and 7h AM (when we are not on office).

I've alread read similar solutions 593140 and 184816 but I was looking for a libvirt or virsh solution instead of install a monitoring tool on each guest.

Server: Ubuntu SAMBA 3 Client: Ubuntu 12.04

I can access the shares using Nautilus but I can't mount the same share using shell.

I issue the following command:

sudo mount -t cifs //auth.local/Aplicacao /home/josir/fontes -o rw,credentials=/home/josir/.smbcredentials,iocharset=utf8,codepage=unicode,uid=1000,gid=1000

The share is mounted but I could not see any subdirectory. I tried to find out why issuing:

josir@MEDIA35:$ ls -ls | grep fontes
0 drw-rws--- 13 josir josir      0 Out  4  2011 fontes

josir@MEDIA35:$ ls -ls fontes
ls: impossível acessar fontes/Software: Permissão negada
ls: impossível acessar fontes/Doc: Permissão negada
ls: impossível acessar fontes/Scripts: Permissão negada
ls: impossível acessar fontes/HmlFontes: Permissão negada

What am I missing ?

What's the correct mount command to get access to this samba share?

Do I have to use the same uid/gid of the samba user ?
