Network VM'S problem

[AntoWkill]

Hello,
From yesterday i have problem with all VMS that after about 20 minute goes offline. I use OVH and every vm's have different and dedicated ip. The dedicated server network is up, only the vms go down, all together and if you login in vm with console and send: ifup eth0 network go ON and after about 20 minute go down again.. Any ideas of the problem?


Thank

Hi,
do you have SLA monitoring online (OVH option) and do you have activate the PVE firewall?
If yes OVH will reboot your sever because they can't ping you and think your machine are dead.
