So, this update only have to be done on HOST, no on each GUEST? With this update, the kernel update on HOST and GUEST, protection is complete against the 3 variants?

Hi all I am a few confused with the new vulnerabilities and want to create a POST to obtain some help from more experimented profesional and hope that this post can also help to more proxmox novice user as it's my case. I understand that there is 2 vulnerabilities, Meltdown and spectre, with 2...

It's very dificult to change all servers of one buissness in some case, in our case, we are working with DELL C6220 (cpu E5-2650) and change all server (very hight price) and move all (a lot of time), it's not so facil :-( but I understand perfectly your opinion, for now I am trying to find the...

:'-(... Thanks to clarify the situation, so in our case with centos (we use cloudlinux that is based on centos), I suppose that only lvm is posible to resize online...

@fabian I know that all we HAVE to upgrade kernel, but because there is a lot of KVM in some production HOST, it's dificult for us to do it yet and had to wait sometime more. The question is, if all KVM are updated and noone have access to GUI / ssh host proxmox, I understand that risk is very...

It seem that it's not possible in centos, wait your test to confirm it, thanks again!

Well, I have tried to do it with gdisk but after do it and reread with partprobe : Error: Partition(s) 1 on /dev/sda have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use. As a result, the old partition(s) will remain in use. You...

Hello I am do some test, with gparted, putty with X11 activated, and VcXsrv on windows, I obtain gparted windows, but with very unusable chars : http://hpics.li/6441773 do you have some solution for this?

Hello I understand that proxmox must also solve the bug, but, is there a so hight risk if all VM have been parshes?

Of course, but you can do it all without any reboot ni impact about services, you can do it in an production server... With ext4, I think you had to do it offline with gparted or similar.

Ok, thanks a lot for your answer! I would have confirmation from expert about this before choosing system of these new server and choosing the install on lvm... change server size disk without reboot is an very great things with LVM!

Yes, but I talk about the guest KVM over the host proxmox with LVM... It's an bad idea and had to be ext4? or LVM will don't (or very less) affect the performance of KVM guest?

Hello Due to the fu$%·$%... increase price of plesk, I will rebuid all our shared hosting servers, join a lot of smaller server on less but more powerfull server to save money on licence. I work with cloudlinux actually on each shared hosting, in ext4 filesystem. I have other smaller VPS in...
