I've been running VMware Server. ESXi is a bit more limited hardware wise than I'd like. I also like the idea of being able to do what I want with the host software. So far though, the only thing I really run directly on the host is ntpd (which the guests use to sync time). I've thought about alternatives, but nothing has seemed very mature.

[qmailtoaster] Re: QMT on Xen? (I hope not)
Nothing necessarily in particular. Just like to keep my options open, in case I decide that I'd like to run some software on the directly on the host along side of VMware-server. My host OS is CentOS, so packages are readily available for it. One thing I do run is ntp server. I believe VMware recommends this for ESXi as well. ESXi doesn't appear to like all of my hardware. I have one host with a USB ethernet dongle that is not used by the host, but is bridged to a guest. I had to get the driver for the device from the EPEL repo. Works fine with VMware Server on CentOS, but I doubt getting it to work with ESXi would have been so easy, if even possible. I tried loading ESXi on one of my test hosts, and it didn't like the on board ethernet at all. I pretty much gave up on ESXi at that point, at least until I get some juicier hardware. -- -Eric 'shubes' Patrick Ring wrote: I'm curious to know what you need to control that can't be done on ESXi? -Patrick Ring -- Sent from my BlackBerry Wireless Device -Original Message- From: Eric Shubert e...@shubes.net To: qmailtoaster-list@qmailtoaster.com qmailtoaster-list@qmailtoaster.com Sent: Wed Aug 04 20:45:46 2010 Subject: [qmailtoaster] Re: QMT on Xen?

Re: [qmailtoaster] Re: QMT on Xen? (I hope not)
I've heard ESXi 4 fixes some of those issues. (Must have 64bit hardware though) I run some low-end services from the ESXi 3.5 hosts, but not much since there isn't much available support for doing so. I do find my performance is better on ESXi than it was on VMWare Server. But, I'm running on older Proliant DL360/380 G3 servers (dual xeon 2.8) ESXi 3.5 is very picky about hardware Especially hard disk controllers and RAID devices. -Patrick Ring -- Sent from my BlackBerry Wireless Device -Original Message- From: Eric Shubert e...@shubes.net To: qmailtoaster-list@qmailtoaster.com qmailtoaster-list@qmailtoaster.com Sent: Wed Aug 04 22:11:24 2010 Subject: [qmailtoaster] Re: QMT on Xen?
