Hello, 2 weeks ago I updated a virtual openbsd test machine from 4.8 to 4.9. It came with the new vmt driver from dlg@ which is is a nice and useful feature. But now I saw that it does not work properly with functions in vSphere which uses automated snapshots. (I testet it with VMware Data Recovery and cloning) In both cases I get "Protocol error from VMX".
Disabling vmt in the kernel is a workaround for the problem. I saw that there was no further development in the driver (looked at http://openbsd.org/plus.html) but maybe someone is interested to have a deeper look as I am not the only person having this issue ( http://communities.vmware.com/thread/317068 ) For now (and maybe until the end of computers ;-) ) I will live without this driver as it is a "nice to have" and not a "must have". thanks guido Here comes the dmesg with diabled vmt: OpenBSD 4.9 (GENERIC) #671: Wed Mar 2 07:09:00 MST 2011 dera...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC cpu0: Intel(R) Xeon(R) CPU E5520 @ 2.27GHz ("GenuineIntel" 686-class) 2.27 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,SSE3,SSSE3,CX16,SSE4.1,SSE4.2,POPCNT real mem = 267939840 (255MB) avail mem = 253427712 (241MB) mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 10/13/09, BIOS32 rev. 0 @ 0xfd780, SMBIOS rev. 2.4 @ 0xe0010 (98 entries) bios0: vendor Phoenix Technologies LTD version "6.00" date 10/13/2009 bios0: VMware, Inc.
