I've also seen randomly loose connectivity issue - with ESXi and CloudStack system VMs. For me, it was not cloudstack related, but something with my network and debian.
It was reverse ARP related and I no longer see this issue (since that test env has been decommissions), but here is what I would try - as a test - create a cronjob on system vms and continuously ping cloudstack management server (or something few hops away). Give this couple of hours and see if you lose connectivity again. > -----Original Message----- > From: Gaspare A Silvestri [mailto:g.silves...@netsons.com] > Sent: Monday, August 05, 2013 3:15 AM > To: users@cloudstack.apache.org > Subject: Re: CS 4.1 + vSphere 5.1 - System VMs issue > > Hello everybody, > > is there anybody who can help me with my previous requests? > > Thanks in advance, > > Gaspare > > On 04/08/2013 12:11, Gaspare A Silvestri wrote: > > Hello everybody, > > > > I've configured the parameters we talked about (Host configured with > > the CS Management private address), with no luck. > > > > If I manually force the gateway for the private and public interfaces > > on both SSVM and Console Proxy VM, I'm able to interact with the > > machines, but I'm still not able to interact with the machine's > > consoles; moreover, the system machines randomly loses their > connectivity. > > > > In your opinion, could I use an external gateway / router (such as > > pfSense or something similar) to route the traffic between the POD and > > the Guest networks?
