启动virt-manager后报错：Error polling connection 'qemu:///system': internal error: Socket 8442 can't be handled (max socket is 4095)

解决办法：

升级libvirt版本，步骤

yum install -y wget 

wget https://libvirt.org/sources/libvirt-4.7.0.tar.xz --no-check-certificate

yum install -y gcc libnl-devel libxml2-devel yajl-devel device-mapper-devel libpciaccess-devel libnl3-devel netcf-devel gnutls gnutls-devel yajl-devel

xz -d libvirt-4.7.0.tar.xz

tar -xvf libvirt-4.7.0.tar

 ./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc

另外说明

如果是ARM架构的机器，出现

Warning: Failed to setup UEFI for AArch64: Did not findany UEFI binary path for arch aarch64'Install options are limited.

运行命令即可

yum install AAVMF-20180508-6.gitee3198e672e2.el7.noarch
