Phenomenon: When virt-install creates a new virtual machine, prompt Host does not support any Virtualization options.
environment: CentOS7, KVM, CPU: Intel(R) Xeon(R) CPU e5-2609,
qemu-kvm, qemu-kvm-tools, virt-manager, libvirt virt-install four major components have been normally installed,
selinux has been closed, iptables have been fully released,
processing steps:
1. General step, advanced BIOS to see whether the CPU is on virtualization, confirm that
2, grep-e ‘(VMX | SVM)’ /proc/cpuinfo, check whether there is echo information, found that there is, also means that step 1 is not blind. Grep KVM
3, dmesg |, grep KVM, the actual function is the same as step 1 and step 2, confirm again whether the host supports virtualization, if not, KVM :disabled by BIOS will be displayed, here I do not have any echo. 4. At this point, the usual solutions on baidu and Google have come to an end and the problem has not been solved… Only themselves to think of a way, here a little fooling around step ten thousand steps.
5, systemctl status libvirtd suddenly found that there was an error in the libvirt log:
internal error: Failed to probe QEMU binary with QMP: /usr/libexec/ qem-kvm: relocation error: /lib64/ libspy-server. so.1
.
6, baidu learned that spice server is provided as a library for qemu use, compiled is libspice server.
, however, is a completely unknown thing to debug and debug, so let’s see if qemu- KVM has any problems.
7, ll /usr/libexec/qemu- KVM first see if qemu- KVM has execution permissions, found that there is, then normal.
8, /usr/libexec/qemu-kvm –version run manually, find error:
version libssl.so.10 not defined in file libssl.so.10
9, still get the solution through baidu solution:
/usr/libexec/qemu-kvm –version normal display version
virt-install
failure solved successfully!
/usr/libexec/qemu-kvm –version
virt-install
failure solved! Thank:
