[CentOS-virt] CentOS on a stick

2011-07-07 Thread Dennis Jacobfeuerborn
Hi, I'm looking into setting up a redundant firewall and I'm wondering how feasible it is to use an USB stick as the only storage device in these systems (i.e. no HDs). The logs will go to a remote logging server but I'm wondering what else needs to be changed to make something like this

[CentOS-virt] Time lagging on DomU

2011-03-17 Thread Dennis Jacobfeuerborn
Hi, on one of our systems I see that while the time on the Centos 5.4 Host is correct it lags behind on two of the 5.5 guests by almost 5 minutes but is correct for the third domU. From what I understand the clock of the system is controlled by the host and and guest cannot write to it (and

[CentOS-virt] Storage performance

2010-12-11 Thread Dennis Jacobfeuerborn
Hi, I recently did some benchmarking on a Rackspace VM and was surprised that bonnie++ showed a read throughput of almost 500MB/sec. Does anyone have an idea how they achieve these speeds in a shared environment? While you can achieve this with a RAID easily these days once you have lots of VMs
