Hi, Upadted from ovirt-engine 3.1.0-1.fc17 to 3.1.0-2.fc17. Now, when I add hosts, it fails with missing cpuFlags "vmx". New host is running -- vdsm 4.10.0-6.fc17 qemu-kvm-1.0-18.fc17. and the output of vdsClient -s 0 getVdsCaps is - clusterLevels = ['3.0', '3.1'] cpuCores = 1 cpuFlags = fpu,de,pse,tsc,msr,pae,mce,cx8,apic,mtrr,pge,mca,cmov,pse36,c lflush,mmx,fxsr,sse,sse2,syscall,nx,lm,up,nopl,pni,cx16,hypervisor,lahf_lm cpuModel = QEMU Virtual CPU version (cpu64-rhel6) cpuSockets = 1 cpuSpeed = 1999.980 emulatedMachines = ['pc-0.15', 'pc-1.0', 'pc', 'pc-0.14', 'pc-0.13', 'pc -0.12', 'pc-0.11', 'pc-0.10', 'isapc'] guestOverhead = 65 hooks = {} kvmEnabled = false lastClient = 192.168.68.235 lastClientIface = ovirtmgmt management_ip = memSize = 7987 netConfigDirty = False On the older host (which was working, I had) - qemu-kvm-1.0-17.fc17 vdsm-4.10.0-5.fc17 and its output of vdsClient -s 0 getVdsCaps is - clusterLevels = ['3.0', '3.1'] cpuCores = 1 cpuFlags = pge,clflush,syscall,tsc,vmx,cmov,fpu,lm,msr,nx,fxsr,pae,nopl,mmx,cx8,mce,de,mca,pse,pni,apic,sse,lahf_lm,sse2,hypervisor,up,cx16,pse36,mtrrmodel_486,model_pentium,model_pentium2,model_pentium3,model_pentiumpro,model_qemu32,model_coreduo,model_core2duo,model_n270,model_Conroe,model_Penryn,model_Nehalem,model_Opteron_G1 cpuModel = Intel(Fake) CPU cpuSockets = 1 cpuSpeed = 1999.980 emulatedMachines = ['pc-0.15', 'pc-1.0', 'pc', 'pc-0.14', 'pc-0.13', 'pc-0.12', 'pc-0.11', 'pc-0.10', 'isapc'] guestOverhead = 65 Is this a new issue? Should we open a BZ? -Sharad
