You can use /var/preserve/ folder to dump image files, I guess you should be able to get the image from this path after upgrade also

 

Thank you

i have  performed software upgrade after upgrading vm os  but it failed again with same message. 

Checking vmhost version compatibility
VMHost version too old for Junos
ERROR: package junos-x86-64-17.4R2.4 fails requirements
ERROR: Failed to add junos-install-mx-x86-64-17.4R2.4.tgz


I will again perform vm os upgrade and will share the logs.

P.S - This is native router and i had performed vm os software upgrade but looks like it did not went through.

Hi,

 

Just noticed you were using "junos-vmhost-install-mx-x86-64-17.4R2-S6.tgz" or "junos-install-mx-x86-64-17.4R2.4.tgz"

 

Can you please use Main Release once:

"junos-vmhost-install-mx-x86-64-17.4R2.4.tgz"

 

Instead of Service Release :

"junos-vmhost-install-mx-x86-64-17.4R2-S6.tgz"

"junos-install-mx-x86-64-17.4R2.4.tgz"

 

 

For instance:

  • "request vmhost software add /var/tmp/junos-vmhost-install-mx-x86-64-17.4R2.4.tgz re0 no-validate"

 

This upgrade installs the host image along with the compatible Junos OS.

If you have important files in directories other than /config and /var, copy the files to a secure location before upgrading the device. The files under /config and /var (except /var/etc) are preserved after the VM host upgrade.
