Hi,

When I created a virtual machine, an error occurred after booting:

No valid host was found.

 

I check a tutorials online:

1. https://specs.openstack.org/openstack/nova-specs/specs/train/implemented/cpu-model-selection.html

2. https://specs.openstack.org/openstack/nova-specs/specs/train/implemented/cpu-model-selection.html

 

a . cat /proc/cpuinfo (View the host's flag)

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,rep_good,nopl,cpuid,extd_apicid,tsc_known_freq,pni,pclmulqdq,ssse3,fma,cx16,sse4_1,sse4_2,x2apic,movbe,popcnt,aes,xsave,avx,f16c,rdrand,hypervisor,lahf_lm,cmp_legacy,cr8_legacy,abm,sse4a,misalignsse,3dnowprefetch,osvw,topoext,ibpb,vmmcall,fsgsbase,bmi1,avx2,smep,bmi2,rdseed,adx,smap,clflushopt,sha_ni,xsaveopt,xsavec,xgetbv1,arat

 

b . I modified the nova.conf

[libvirt]

cpu_mode = custom

cpu_models = SandyBridge,IvyBridge,Haswell,Broadwell

 

c .I modified the flavor

|trait:HW_CPU_X86_AVX='required',trait:HW_CPU_X86_AVX2='required' |

 

d . openstack server create

 

When I started the instance, an error occurred  

e . openstack server show vm9

I read the error message in the log, and we think there are several errors that may cause the problem.

Basic Env informations:

1. Ubuntu18.04

2. Openstack(train)

 

Could you provide me with some help, thank you!
