在 RHEL KVM（x86_64）上运行的 Ubuntu 客户机失败了。

Question

我有一台x86_64机器，成功安装了Sles12和RHEL7客户机。但是在创建Ubuntu客户机（64位）时失败了。

virt-install --name=ubuntu1 --virt-type=kvm --boot cdrom,hd --network=default,model=virtio --disk /dev/dm-13,size=300,format=raw,bus=virtio,cache=none,sparse=true --memory=8192 --vcpu=2 --location=/home/suse/ubuntu-16.04-server-amd64.iso  --console pty,target_type=serial --graphics none --extra-args 'console=ttyS0,115200n8 serial'
Starting install...

ERROR    Couldn't find hvm kernel for Ubuntu tree.

    kvm                   525259  1 kvm_intel

在调试时，这个程序期望使用i386架构吗？

请问有人能提供建议吗？

从调试中可以看到它确实在寻找默认的架构。

askubuntu问答中已经解决了完全相同的问题，并且已经通过补丁正确地从ISO名称中检测架构。

带有此补丁的virt-manager没有官方发布，因此需要从源代码运行virt-manager或通过更改和编译/usr/share/virt-manager/virtinst/urlfetcher.py文件来处理现有安装。
