Linux KVM来宾操作系统启动错误

Linux KVM来宾操作系统启动错误,linux,permissions,qemu,kvm,libvirt,Linux,Permissions,Qemu,Kvm,Libvirt,我正在尝试启动来宾操作系统以继续我的工作,但我的virsh安装有问题。 以下是安装脚本的一部分: qemu-img create -f qcow2 -o preallocation=metadata ~/images/${vm_name}.qcow2 ${pool_size}G # create dir for images mkdir ~/images/ virt-install \ --connect qemu:///system \ --name $vm_name \ --ram 10

我正在尝试启动来宾操作系统以继续我的工作,但我的virsh安装有问题。 以下是安装脚本的一部分:

qemu-img create -f qcow2 -o preallocation=metadata ~/images/${vm_name}.qcow2 ${pool_size}G

# create dir for images
mkdir ~/images/

virt-install \
--connect qemu:///system \
--name $vm_name \
--ram 10240 \
--vcpus 4 \
--disk ~/images/${vm_name}.qcow2,size=$pool_size,bus=virtio,sparse=false,format=qcow2 \
--network network=default,model=virtio \
--location http://ua.archive.ubuntu.com/dists/trusty-updates/main/installer-amd64/ \
--initrd-inject=$current_dir/preseed.cfg \
--extra-args="file=file:/preseed.cfg vga=788 quiet console=tty0 utf8 console=ttyS0,115200" \
--os-type=linux \
--virt-type kvm \
--video=vga \
--noreboot \
--cpu host \
--hvm

virsh start $vm_name
echo "----------Login to console----------"
virsh console $vm_name
当我尝试将此脚本作为文件运行(如./script.sh)时,会产生一个错误:

Formatting '/home/{username}/images/test.qcow2', fmt=qcow2 size=53687091200 encryption=off cluster_size=65536 preallocation='metadata' lazy_refcounts=off refcount_bits=16
mkdir: cannot create directory '/home/flash/images/': File exists
ERROR    'DebianDistro' object has no attribute '_prefix'
error: failed to get domain 'test'
error: Domain not found: no domain with matching name 'test'

----------Login to console----------
error: failed to get domain 'test'
error: Domain not found: no domain with matching name 'test'
ERROR    internal error: process exited while connecting to monitor: Could not access KVM kernel module: Permission denied

我已经尝试使用本指南重新安装kvm qemu包- 一切顺利完成。 我确信该脚本将像我以前在另一台机器上使用它一样工作,不会出现任何问题

另一种尝试: 使用下面的脚本

virt-install --connect qemu:///system -n test -r 10240 \
--vcpus=4 \
--disk path=/data0/images/test.img,size=50,format=qcow2,bus=virtio,cache=none \
--cdrom /home/{username}/Downloads/kvm/ubuntu-14.iso \
--vnc \
--os-type=linux \
--accelerate \
--network network=default \
--hvm
产生一个错误:

Formatting '/home/{username}/images/test.qcow2', fmt=qcow2 size=53687091200 encryption=off cluster_size=65536 preallocation='metadata' lazy_refcounts=off refcount_bits=16
mkdir: cannot create directory '/home/flash/images/': File exists

另外,当我试图通过virt install--os variant list列出所有操作系统变体时,它无法识别此命令,并试图启动来宾操作系统,而不是列出变体

您能帮我找出这里的问题吗?

要修复此错误:

ERROR    'DebianDistro' object has no attribute '_prefix'
编辑文件
/usr/share/virt manager/virtinst/urlfetcher.py
,并在第1034行中更改此文件:

if self._prefix:
为此:

if self._url_prefix:
