Generally, I have not had any problems with this configuration. However one particular VM, which is running the same kernel and same VMware settings as the other VMs has paniced twice in the past few months. I do not have a core dump, but both times a message regading the CD-ROM device was logged shortly before the panic: Sep 9 08:50:56 shellvm kernel: ata1: WARNING - READ_TOC read data overrun 18>12 Prior to the panic, the only thing Ive observed via my normal nagios checks was that snmp and other network services became unavailable and ping times to the host became very erratic, jumping from a few ms to 800ms+. After the panic, the VM is locked up hard and consuming copious amounts of CPU. Looking around I see two things of note: https://communities.vmware.com/message/1876880 (suggests it=92s an issue with FreeBSDs CD-ROM handling) = http://freebsd.1045724.n5.nabble.com/Re-kern-150186-parallels-panic-Parall= els-Desktop-CDROM-disconnected-leads-to-panic-eventually-td4114484.html (also suggests CD issues) This thread also ends with Ivan Voras stating "I'd say it's 'well known' - at least the panic also happens on VMWare, and has been happening for many years. Ill try the suggested fix of completely removing the CD-ROM device (its currently in the device list, but is not connected), but Im curious if theres any reference Ive missed regarding known VMware issues and/or best practices. Ill be sure to grab a console screenshot if it happens again, I have little hope of getting a dump though, as it seems the whole IO system is locked up.
