Are you asking me how to copy files from one computer to the other? Typical commands: rsync, sftp, scp. You may also have NFS or Windows shares (SMB or Samba).

Just remove them. Libvirt will assign new ones.

Hello every body

I installed a vmware in my PC (OS WIN10).

I create a VM (Redhat7) in vmware and i want to use virt-manager in this redhat7 os.

to do that, i used this commande to see if my CPU support the virtualization:

$ egrep -E -c "SVM|VMX" /proc/cpuinfo
1
$

What does mean this result ?

Thanks

The CPU has virtualization extensions, i.e. instructions that greatly improve the efficiency of the VM hypervisor. To learn more: https://en.m.wikipedia.org/wiki/X86_virtualization, in particular the section about hardware-assisted virtualization.

The VM has a harddisk and a DVDROM, but the machine's BIOS or UEFI doesn't find a program on them that can be started. Normally they should contain a bootloader. My guess: The ISO file doesn't match the VM's architecture or is otherwise corrupt.

I suggest an internet search. This is the first search result I get: https://serverfault.com/questions/39...fferent-server.

It seems you need to install ntfs.

EDIT: Why don't you perform an internet search for the error message? You will get a faster result than by posting on Linuxquestions.

Hello

Thank you for this precious advice.

Also I managed to create a virtual machine using qemu-kvm.
So I managed to make a clone of this VM.

Thank you for your precious help.

But now I want to learn how to copy a RedHat VM from one server and install it in another using the same qemu-kvm hypervisor.

Can you help me do this?

Thanks again

Hello

I have this problem:

[root@localhost ~]# yum install qemu-kvm libvirt
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-
: manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
There are no enabled repos.
Run "yum repolist all" to see the repos you have.
To enable Red Hat Subscription Management repositories:
subscription-manager repos --enable <repo>
To enable custom repositories:
yum-config-manager --enable <repo>

[root@localhost ~]# yum repolist all
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-
: manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
repolist: 0
[root@localhost ~]#

What does mean please and how can i install the package ?

thanks

That is a problem with commercial products. "This system is not registered with an entitlement server. "

Contact your Red Hat support specialist for this issue or consider using a different linux distro.
