내 Virtual Bastion 서버에는 8개의 디스크가 있고 해당 PCI 주소는 물론 이를 제어하는 호스트 ID도 여기에서 공유됩니다. 그러나 lspci세 개의 드라이브 컨트롤러가 나열되어 있습니다. 나머지 2개는 전혀 사용하지 않고 SCSI Controller: LSI Logic여기서만 사용한다는 뜻인가요? 사용만 된다면 왜 존재할까요 host0 and other hosts?host2

답변1
host0그리고 host1이것으로부터:
00:07.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01)
VMware 가상 CD/DVD 에뮬레이션을 지원합니다. 컨트롤러의 물리적 버전에는 두 개의 IDE 채널이 있으며, 제가 정확하게 기억한다면 VMware에서는 최대 두 개의 가상 CD를 동시에 사용할 수 있습니다.
실제 디스크 장치는 현재 다음 중 하나를 /dev/sd*통해 있는 것으로 보입니다 .host2
00:10.0 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 01)
이는 호환성을 극대화하기 위한 VMware의 단순 병렬 SCSI 컨트롤러 에뮬레이션입니다.
host3... host32그와 관련하여 VMware SATA AHCI controller실제 디스크를 렌더링하지 않는 것 같습니다.
일부 메모리를 소비하는 것 외에는 해를 끼치지 않지만 VMware 호스트 관리자에게 가상 시스템의 구성을 검토하고 불필요한 경우가 아니면 현재 사용하지 않는 가상 SATA AHCI 컨트롤러를 가상 하드웨어 구성에서 제거하도록 요청할 수 있습니다.
아마도 호스트 관리자는 이전 유지 관리 중단 중에 컨트롤러 유형을 업그레이드하려고 했지만 VM이 VMware PVSCSI 또는 기타 최신 디스크 컨트롤러 유형을 지원하도록 구성되지 않았기 때문에 변경 사항을 롤백해야 했을 수 있습니다.
최대 성능을 위해서는 PVSCSI가 최선의 선택인 것 같습니다.가상 머신과 호스트 간의 작업 중복을 제거하기 때문입니다.
답변2
vmware에서도 비슷한 문제가 있었는데 SCSI 장치가 전혀 연결되어 있지 않았지만 Linux에서는 놀라운 양의 SCSI 장치가 나타났습니다 /dev/sdg. 예를 들어 내 디스크는 IDE이므로 machine.vmx편집 scsi0.present = "TRUE"하고 "FALSE". 이것은 내 문제를 해결했습니다.
