tl;dr : Is it possible to dump the memory of a live VM and then use that memory with a copy of the same VM.



I have a running VM for which I did virsh save myvm which created a file.
With this file, I can easily do virsh restore file to have the VM immediately ready with RAM loaded.



Now, I'd like to make copies of this VM. I use qemu-img create -f qcow2 -b myvm.qcow2 newvm.qcow2 (use myvm.qcow2 as a backing file).
For this new VM, I'd also like to already load the memory, skipping the boot step of the VM.



I tried to virsh restore newvm --xml newvm.xml where newvm contains a new uuid and points to the newvm.qcow2, however libvirt does not allow this: unsupported configuration: Target domain uuid xx does not match source yy




qemu libvirt virsh

          Postfix configuration issue with fips on centos 7; mailgun relay

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
