Pono wau e hōʻike i kahi dashboard me ka nānā ʻana i kekahi mau pale ma ke keʻena. Aia kekahi mau Raspberry Pi Model B + kahiko a me kahi hypervisor me kahi kumu palena ʻole.
ʻIke ʻia ʻaʻole lawa ka randomness o ka Raspberry Pi Model B+ e hoʻomau i ka holo mau ʻana o ka polokalamu kele pūnaewele a hāʻawi i nā kiʻi he nui i loko, no ka mea, he hapa ka ʻaoʻao o ka ʻaoʻao a hāʻule pinepine.
Aia kahi hopena maʻalahi a nani, makemake wau e kaʻana like me ʻoe.
E like me kāu e ʻike ai, loaʻa i nā Raspberry āpau kahi kaʻina wikiō ikaika loa, maikaʻi loa ia no ka decoding wikiō hāmeʻa. No laila ua hiki mai ka manaʻo e hoʻomaka i kahi polokalamu kele pūnaewele me kahi dashboard ma kahi ʻē aʻe, a hoʻouna i kahi kahawai i mākaukau me kahi kiʻi i hāʻawi ʻia i ka raspberry.
Eia hou, pono e hoʻoponopono maʻalahi kēia, no ka mea ma kēia hihia e hana ʻia nā hoʻonohonoho āpau ma kahi mīkini virtual, ʻoi aku ka maʻalahi o ka hoʻonui a me ka hoʻihoʻi.
ʻAʻole i ʻōlelo koke ʻia.
ʻāpana kikowaena
Hoʻohana mākou i ka mākaukau . ʻAʻole pono e hoʻokomo, aia nā mea a pau āu e pono ai e hoʻonohonoho wikiwiki i kahi mīkini virtual, a kōkua e hoʻonohonoho koke i kahi pūnaewele, hoʻohui i nā kī ssh a hoʻokomo koke i ka hana.
Hoʻonoho mākou i kahi mīkini virtual hou a hoʻokomo mua iā ia ma luna , и :

ʻaoʻao mea kūʻai aku
ʻOi aku ka maʻalahi ma aneʻi, e like me kaʻu i ʻōlelo ai, e hoʻohana mākou i ka Raspberry Pi Model B +.
ʻO ka mea mua, e hoʻokomo kākou , no keia ke hahai nei makou ma ka pūnaewele mau.
