5888	Unable to start 64 bit vm with 3.1.2	Keyzer Suze		"Hi

VB keeps saying it can't start VM because VT-x is not available 

I have upgraded to 3.1.2 from 3.0.8 (from your debian repository)

head -n 8  /proc/cpuinfo 
processor	: 0
vendor_id	: AuthenticAMD
cpu family	: 16
model		: 4
model name	: AMD Phenom(tm) II X4 945 Processor
stepping	: 2
cpu MHz		: 800.000
cache size	: 512 KB

grep svm /proc/cpuinfo 
flags		: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm 3dnowext 3dnow constant_tsc rep_good nonstop_tsc extd_apicid pni monitor cx16 popcnt lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs skinit wdt

and I have it turned on in my bios (this used to work with 3.0.8)

I have attached Vbox.log
