我想使用virsh删除libvirt的dhcp租约条目。

$ virsh net-list
Name                 State      Autostart     Persistent
----------------------------------------------------------
default              active     yes           yes
docker-machines      active     yes           yes

$ virsh net-dhcp-leases docker-machines
Expiry Time          MAC address        Protocol  IP address               Hostname        Client ID or DUID

我使用virsh net-update delete尝试了其他选项，但我不断收到此错误：

couldn't locate a matching dhcp host entry in network 'docker-machines'

这是因为libvirt的租约文件已更改（它们以网络接口命名并且格式为JSON）？如果是这样，那我该怎么办呢？

Answer 1

动态租约很难使用virsh删除。

删除var / lib / libvirt / dnsmasq / virbr0。*文件将适用于默认网络。假设所有功能均已关闭，即所有虚拟机均已关闭

sudo rm var/lib/libvirt/dnsmasq/virbr0.*
