There are many kinds of Xen: HVM, PV and PVHVM. I have PV, so the existing detection may still work with HVM and PVHVM flavours. /sys/class/dmi folder doesn't exist. /sys/class contains the following folders, most of them empty: backlight/ firmware/ leds/ power_supply/ vtconsole/ bdi/ gpio/ mem/ rtc/ watchdog/ block/ graphics/ misc/ thermal/ bsg/ hwmon/ net/ tty/ dma/ input/ pci_bus/ vc/ dmidecode says the following: # No SMBIOS nor DMI entry point found, sorry. /proc/cpuinfo contains the following flags: flags : fpu de tsc msr pae cx8 sep cmov pat clflush mmx fxsr sse sse2 ss ht nx constant_tsc nonstop_tsc pni pclmulqdq ssse3 sse4_1 sse4_2 popcnt aes hypervisor Not sure how these translate to CPUID flags but note the hypervisor flag.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
