I ka mua ua noʻonoʻo ʻia nā koho no ka mea e hiki ke hoʻololi ʻia nā ʻōnaehana i kēia manawa ma ke ʻano he ʻāpana o ka hoʻokō ʻana i ke kauoha hoʻokomo. E kālele ana nā ʻatikala aʻe i ke koho ʻana i nā huahana kikoʻī e pani i nā mea i hoʻoili ʻia i kēia manawa. E hoʻomaka kākou me ka hoʻomaka - ka ʻōnaehana virtualization.
1. Ka eha o ke koho
No laila, he aha kāu e koho ai? IN :
- Pūnaehana virtualization server "R-Virtualization» (libvirt, KVM, QEMU)
- Pūʻolo polokalamu "Nā mea hana virtualization Brest» (libvirt, KVM, QEMU)
- Papahana no ka mālama ʻana a me ka nānā ʻana i ke kaiapuni virtualization "Sharx Stream" (he hoʻonā kapua i kūpono ʻole no nā keʻena aupuni ma 95% o nā hihia (huna, etc.)
- Pūʻulu polokalamu no ka virtualization o nā kikowaena, nā papa kuhikuhi a me nā noi "HOME" (KVM x86)
- Pūnaehana no ka mālama pono ʻana i ke kaiapuni virtualization "Z|virt"(aka oVirt+KVM)
- ʻōnaehana hoʻokele kaiapuni virtualization "ʻO ROSA Virtualization"(aka oVirt+KVM)
- Mea nānā hoʻi QP VMM (e like me ka Oracle Virtual Box e like me nā mea ʻē aʻe)
Hiki iā ʻoe ke noʻonoʻo i nā hypervisors i hoʻokomo ʻia i ka mahele OS a i ʻole i loko o kā lākou waihona. No ka laʻana, loaʻa iā Astra Linux ke kākoʻo KVM. A no ka mea ua hoʻokomo ʻia i loko o nā waihona waihona OS, hiki ke manaʻo ʻia he "pono" no ka hoʻokomo ʻana a me ka hoʻohana. "He aha ka mea hiki ke hoʻohana ʻia ma ke ʻano o ka hoʻokomo ʻana a me ka mea hiki ʻole" i kūkākūkā ʻia ma mua , no laila ʻaʻole wau e noʻonoʻo i kēia pilikia.
ʻOiaʻiʻo, maanei :
- ʻO VirtualBox
- Luna hooponopono (KVM) Aeto au
- ponoʻewa ma luna o KVM
ʻAʻohe papa inoa o ROSA Linux, akā hiki iā ʻoe ke loaʻa ma ka wiki :
- ʻO ROSA Virtualization ma luna o oVirt ma luna o KVM
- QEMU ma luna o KVM
- oVirt 3.5 ma luna o KVM
He helu kēia
Ua like ka Alt Linux
1.2. Aia kekahi AKA
Ma ka nānā pono ʻana, manaʻo mākou e hana mākou i kekahi mau hypervisors kaulana, ʻo ia hoʻi:
QEMU He polokalamu manuahi a wehe ʻia no ka hoʻohālikelike ʻana i nā lako o nā ʻano like ʻole, hiki ke hana me ka ʻole o ka hoʻohana ʻana i ka KVM, akā ʻo ka hoʻohana ʻana i ka virtualization hardware e wikiwiki nui i ka hana o nā ʻōnaehana malihini, no laila ʻo ka hoʻohana ʻana iā KVM ma QEMU (-enable-kvm) ke koho i makemake ʻia. (c) ʻO ia hoʻi, ʻo QEMU kahi hypervisor ʻano 2, ʻaʻole i ʻae ʻia i kahi kaiapuni huahana. Me KVM hiki ke hoʻohana ʻia, akā i kēia hihia e hoʻohana ʻia ʻo QEMU ma ke ʻano he mea hoʻokele KVM ...
Ke hoʻohana nei i ke kumu ʻO VirtualBox ma ke kalepa maoli : "E hoʻomaka ana me ka mana 4, i hoʻokuʻu ʻia i Dekemaba 2010, ka māhele nui o ka huahana i hāʻawi manuahi ʻia ma lalo o ka laikini GPL v2. ʻO kahi pūʻolo hou i hoʻokomo ʻia ma luna ona, e hāʻawi ana i ke kākoʻo no nā polokalamu USB 2.0 a me 3.0, Remote Desktop Protocol (RDP), drive encryption, booting mai NVMe a me PXE, ua māhele ʻia ma lalo o kahi laikini PUEL kūikawā ("no ka hoʻohana pilikino a me ka loiloi") , ma lalo o ka ʻōnaehana manuahi no ka hoʻohana pilikino, no ka hoʻomaʻamaʻa ʻana, a i ʻole no ka loiloi ma mua o ka hoʻoholo ʻana e kūʻai i ka mana kālepa." (c) ʻO Plus VirtualBox kekahi ʻano hypervisor ʻano 2, no laila nalo pū kekahi.
Hōʻuluʻulu: ma kona ano maemae ia kakou wale no KVM.
2. ʻO ke koena: KVM a i ʻole KVM?
Inā pono ʻoe e hoʻololi i kahi hypervisor "domestic", he liʻiliʻi kāu koho. E lilo ana KVM i hoʻokahi wīwī a i ʻole kekahi, me kekahi mau hoʻololi, akā ʻo KVM mau nō ia. He nīnau ʻē aʻe inā maikaʻi a maikaʻi ʻole paha kēia; ʻaʻohe mea ʻē aʻe.
Inā ʻaʻole koʻikoʻi nā kūlana, a laila, e like me ka mea i kūkākūkā ʻia ma mua : "Pono mākou e lawe i nā hōʻailona i nā palena i hoʻopaʻa ʻia. ʻO kaʻoiaʻiʻo,ʻo ia hoʻi, pono mākou e hoʻololi i ka OS i kēia manawa me nā huahana mai ke Keʻena o Telecom a me Mass Communications kākau inoa a hoʻonui i ka helu o nā pūnaewele hana i hoʻololiʻia i ka 80% .... No laila, hiki iā mākou ke haʻalele i ka pūpū ma Hyper-V. , ʻoiai ua loaʻa iā mākou a makemake mākou iā ia ... "(c) No laila ke alo nei mākou i kahi koho: ʻO Microsoft Hyper-v a i ʻole KVM. KVM malia paha me nā mana "screwed" iā ia, akā e mau nō ia KVM.
ʻAʻole hiki ke hoʻohālikelike ʻia kēia mau huahana ʻAʻole ʻAʻole ...ʻAe, maopopo iā ʻoe...
E pili ana i ka hoʻolālā a me ka hoʻonohonoho KVM ʻaʻole like ke kākau ʻana ʻAʻole ʻAʻole aʻaʻole ... Ma kahi huaʻōlelo, .
Pela no
ʻAʻohe oʻu ʻike i ka hana hou ʻana iaʻu iho a wehewehe i kēia mau ʻōnaehana, hoʻohālikelike, etc. Hiki iā ʻoe, ʻoiaʻiʻo, huki i nā kumu nui mai nā ʻatikala, akā he mea mahalo ʻole kēia i nā mea kākau, manaʻo wau. ʻO ka mea e koho e heluhelu ʻaʻole i kēia wale nō, akā he mauna ʻike hoʻi e hoʻoholo ai i kona manaʻo.
ʻO ka ʻokoʻa wale nō aʻu e makemake ai e nānā i ka failover clustering. Inā ua kūkulu ʻia ʻo Microsoft i loko o ka OS a me ka hana hypervisor, a laila i ka hihia o KVM pono ʻoe e hoʻohana i nā polokalamu ʻaoʻao ʻekolu, pono e hoʻokomo ʻia i loko o nā waihona waihona OS. ʻO ka hui like o Corosync + Pacemaker, no ka laʻana. (ʻaneʻane loaʻa kēia hui ʻana o nā ʻōnaehana hana hale āpau ... ʻo lākou a pau paha, akā ʻaʻole au i nānā i ka 100% o lākou.) Loaʻa pū nā manual no ka hoʻonohonoho ʻana i ka clustering i ka nui.
3. Ka hopena
ʻAe, e like me ka mea maʻamau, ʻaʻole pilikia kā mākou Kulibins, lawe lākou i ka mea i loaʻa iā lākou, hoʻohui i kahi mea liʻiliʻi o kā lākou iho, a hana i kahi "huahana" e like me nā palapala, he home, akā ʻo ka mea maoli ʻo OpenSource. He mea kūpono anei ka hoʻolilo kālā mai ka waihona kālā ma nā ʻōnaehana virtualization "kaʻawale" (heluhelu: ʻaʻole i hoʻokomo ʻia i ka OS)? Mai noʻonoʻo. No ka loaʻa ʻana o ka KVM like, pono ʻoe e uku no ia.
No laila, ke koho ʻana i kahi pani no kahi hypervisor e iho mai i ka OS server āu e kūʻai ai no ka Enterprise a hana. A i ʻole, e like me kaʻu hihia, e noho ʻoe me kāu mea i loaʻa mua (Hyper-VESXi insert_needed).
