Ryzen 5 3500U搭載GMKtec G10 mini上に構築した vSphere ESXi 8.0 Freeの検証環境にて、Proxmox VE 9.1仮想マシン3台構成でクラスタを作成し、HA試験を行ったところ、3台中1台に対して失敗した。
結果を先に書いておくと、Proxmox VE環境上の仮想マシン挙動で発覚したが、実際の問題はvSphre ESXiの仮想CPUの作りの問題でした。
さて、発覚した状況としては、Proxmox VE上でHA設定をしている場合、仮想マシンを動かしていたサーバを停止すると、稼働中のサーバ上で再起動してくるはずが、下記のエラーで起動が失敗していた。
task started by HA resource agent
kvm: warning: host doesn't support requested feature: CPUID.80000001H:ECX.cmp-legacy [bit 1]
kvm: Host doesn't support requested features
TASK ERROR: start failed: QEMU exited with code 1
3台とも仮想マシンの4vCPUにしてるはずなんだけど・・・と思ってCPU設定を見直してみると、ソケット数が違っていた
proxmox1, proxmox2は1ソケット4コア
proxmox3は4ソケット1コア
この影響なのか、/proc/cpuinfoに違いが・・・
proxmox1とproxmox2の/proc/cpuinfo

proxmox3のflagsには「ht」「cmp_legacy」がない。
またproxmox3のbugsには「spectre_v2_user」がある
proxmox3は1つのCPU内に複数のコア/スレッドがないので、hyper thread機能が存在しない、ということで消されていた模様
このため、proxmox3仮想マシンを一度停止し、CPU設定を1ソケット4コアに揃えたところ、flagsに「ht」と「cmp_legacy」が追加されたことを確認した

というわけで、vSphere ESXi 8.0上で「4vCPU」を設定する場合、「1CPU 4コア設定」と「4CPU1コア設定」とで提供されるCPU機能が異なり、一部の挙動が変わる、ということでした。
