關於KVM在NFS環境下運行的問題
我把NFS伺服器的/vps掛載到KVM主機的/mnt上，mnt目錄我已經設成了777了，但是使用virt-install 行創建虛擬機，出現這樣的錯誤：
大俠們，能告訴是什麼原因造成的嗎，如果有這方面經驗，可不可發一份配置我看看
# virt-install
ERROR A name is required for the virtual machine. (use --prompt to run interactively)
# virt-install --prompt
What is the name of your virtual machine? 116.254.191.19
How much RAM should be allocated (in megabytes)? 2048
What would you like to use as the disk (file path)? /mnt/116.254.191.19.s
How large would you like the disk (/mnt/116.254.191.19.s) to be (in gigabytes)? 10
What is the install CD-ROM/ISO or URL? /vps/isos/win2003sp2.iso

by running 'virsh start 116.254.191.19'; otherwise, please
restart your installation.

《解決方案》
selinux策略默認禁止kvm使用nfs資源。我初步推測你的問題是由此導致。
1)
# setenforce 0
2)
編輯 /etc/selinux/config
把 SELINUX=enforcing 改為 SELINUX=disabled
3)
確認 /mnt/116.254.191.19.s 是否存在。請給出ls輸出
4)
重試安裝

感謝版本，的確是這個問題，困擾我挺久拉
《解決方案》
還有一種可能，
禁用nfsv4

I met a similar problem when installing a virtual machine in SUSE12.3 by using interfacial QEMU-KVM, but I could not find a /etc/selinux/config to solve this permission-denied-problem. So I switched to installing it in console expecting to find an easy way to change authorities, accidentally, the problem never show up. Could anybody tell me what happened?
