vm（由libvirt创建）上的archlinux无法启动？

有 vm0x01 的域 xml：

<domain type='kvm' id="1">
    <name>vm0x01</name>
    <uuid>4dea24b3-1d52-d8f3-2516-782e98a23fa1</uuid>
    <genid>915a7887-4603-42a1-b72c-95eb0a87761f</genid>
    <memory unit='MiB'>512</memory>
    <vcpu>1</vcpu>
    <os>
        <type arch='x86_64' machine='pc'>hvm</type>
        <bootmenu enable='yes' />
        <boot dev='cdrom' />
    </os>
    <cpu mode='host-model' />
    <clock offset='utc' />
    <devices>
        <emulator>/usr/bin/qemu-system-x86_64</emulator>
        <disk type='file' device='disk'>
            <driver name='qemu' type='qcow2' />
            <source file='/var/lib/libvirt/images/vm0x01.qcow2' />
            <target dev='vda' bus='virtio' />
        </disk>
        <disk type='file' device='cdrom'>
            <driver name='qemu' type='raw' />
            <source file="/var/lib/libvirt/images/archlinux-2023.08.01-x86_64.iso" />
            <target dev='hda' bus='sata' />
            <readonly />
        </disk>
        <interface type='bridge'>
            <source bridge='ovsbr1' />
            <virtualport type='openvswitch' />
            <mac address='52:54:00:9f:98:c9' />
        </interface>
        <graphics type='vnc' port='5900' autoport='yes' listen='10.10.10.3' />
        <video>
            <model type='qxl' vram='65536' heads='1' />
        </video>
        <rng model="virtio">
            <backend model="random">/dev/urandom</backend>
        </rng>
    </devices>
</domain>

和网络 xml：

<network>
    <name>ovs-nw0</name>
    <forward mode='bridge'/>
    <bridge name='ovsbr1'/>
    <virtualport type='openvswitch'/>
</network>

结果是ip addr：

root@archlinux0x01 ~/develop/lang/rust/virtrunc
  # ip addr

现在，我使用 vnc 客户端连接到 vm0x01。我首先选择的是： 在此输入图像描述 然后，得到的是： 在此输入图像描述 在此输入图像描述

帮助！这实在难倒我了。

答案1

我得到了它！将内存设置为2048MiB后，这个问题就消失了。我不知道最小内存阈值是多少。但看起来我给的内存较少使它不起作用。
