Hi Edison, I have been playing around with DevCloud and I wanted to share my findings here:
1. Needs more memory for guests I'd been getting InsufficientServerCapacityException when I tried launching a VM after rdeploy*, rdebug and adding a basic ZONE. I found that a router VM will be spun up upon launching a VM with CentOS template and total number of VM will be 4 (SSVM, CPVM, Router VM, new instance). Total mem on the host(DevCloud) in the DB is below 400MB(IIRC), and that's not enough for 4 VMs. 2. OOM kills server Often times, inside management server, OOM killer kills management java process. You may want to allocate more memory for the mgmt server and/or add some swap. 3. DNS nat doesn't work on Ubuntu precise(4.1.1878361~Ubuntu~precise) By default, the DNS server nat setting with 10.0.2.3 didn't work and that made it slow to ssh into DevCloud. I found an workaround by running the following command: VBoxManage modifyvm DevCloud --natdnshostresolver1 on Thanks, Tomoe On Wed, Jul 11, 2012 at 9:02 AM, Edison Su <edison...@citrix.com> wrote: > > >> -----Original Message----- >> From: to...@midokura.jp [mailto:to...@midokura.jp] On Behalf Of Tomoe >> Sugihara >> Sent: Tuesday, July 10, 2012 4:40 PM >> To: cloudstack-us...@incubator.apache.org >> Cc: cloudstack-dev@incubator.apache.org >> Subject: Re: [RFC] DevCloud, an all-in-one-box CloudStack development >> environment >> >> On Wed, Jul 11, 2012 at 2:33 AM, Edison Su <edison...@citrix.com> wrote: >> > >> > >> >> -----Original Message----- >> >> From: to...@midokura.jp [mailto:to...@midokura.jp] On Behalf Of >> Tomoe >> >> Sugihara >> >> Sent: Tuesday, July 10, 2012 1:22 AM >> >> To: cloudstack-dev@incubator.apache.org >> >> Cc: cloudstack-us...@incubator.apache.org >> >> Subject: Re: [RFC] DevCloud, an all-in-one-box CloudStack >> development >> >> environment >> >> >> >> On Tue, Jul 10, 2012 at 3:32 AM, Edison Su <edison...@citrix.com> >> wrote: >> >> >> >> > > >> >> > > Not rdeploydb, but successfully ran "rdebug". >> >> > > However, I still can't find ListTemplate even in /var/log/cloud/ >> >> > >> >> > Better to fix rdeploydb at first, right now, your system is in a >> good >> >> shape. >> >> > If you had taken a snapshot for devcloud after importing the >> >> devcloud.ova into virtualbox, then you can revert back to the >> initial >> >> state. >> >> > Then we can test the preinstalled cloudstack mgt server works for >> you >> >> or not, by go to http://localhost:8080/client, then enable the zone, >> >> wait for a few minutes, ssvm will come up, and the tiny user vm will >> be >> >> available. >> >> > Anyway, I'll write up the whole setup/configuration/how-to-use, >> step- >> >> by-step illustrated. >> >> >> >> >> >> Thanks for the writeup.
