Thank you Christophe,

Yes  -  We change .../vendor/src/github.com/intel/govmm/qemu/qemu.go,   "appendBios()"

func (config *Config) appendBios() {
       if config.Bios != "" {
               if config.Knobs.MemEncrypt == true {
                       config.qemuParams = append(config.qemuParams, "-drive")
                       config.qemuParams = append(config.qemuParams, fmt.Sprintf("if=pflash,format=raw,unit=0,file=%s,readonly", config.Bios))

                       config.qemuParams = append(config.qemuParams, config.Bios)
               }
       }
}

But then "containerd" does not use this method ?

Hi All,

I may have mixed up my working and not working cases - sorry about 
this, I have finally isolated my working and not-working cases, (for sure) as follows :

This seems consistent with what we deduced from the earlier exchanges.

In short:

I believe this was your 1.x demo, right?

Now, this -drive is good, but it is unexpected, because I see nowhere in the normal Kata code that would emit that. This suggests you use a version I don't know about, or maybe that there is for example a patch that was sent to a release but dropped from the 2.0 branch.

Further, please note that Laszlo Ersek seems to imply in a parallel thread that -drive is no longer the right way to do it either. We may need to implement qemu-version dependent options.

As Fabiano pointed out (indirectly), there is no "-bios" option in the 
command line above. So either

I'm sorry, Fabiano pointed out that I somehow had managed to miss the -drive if=pflash,format=raw,unit=0,file=/usr/local/share/qemu/OVMF_CODE.fd.kata,readonly option. Not enough coffee, I guess.

There is something mysterious about this, as I pointed out in https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fkata-containers%2Fkata-containers%2Fissues%2F1231%23issuecomment-755333403&amp;data=04%7C01%7Csandeep.gupta%40amd.com%7C3d884bd4e4904f858e6308d8b2e83de9%7C3dd8961fe4884e608e11a82d994e183d%7C0%7C0%7C637456057849018749%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&amp;sdata=6Gm0u0gxkCbpYwD6eSnpi99BtnGszhvyWVV%2Bzfs2dMc%3D&amp;reserved=0. Basically, govmm does not seem to emit that option.

func (config *Config) appendBios() {
if config.Bios != "" {
config.qemuParams = append(config.qemuParams, "-bios") 
config.qemuParams = append(config.qemuParams, config.Bios) } }

It apparently has always been like this. Do you remember either patching that file, or maybe finding some other way to pass the OVMF arguments to qemu (like using a qemu wrapper)?



Disregard what is below. Instead, now we have an observable command-line difference between 1.x and 2.0. My guess is that this explains why you have trouble with 2.0. Even if my own quick experiments today showed that you can boot an OVMF with -bios, I'm not sure you can get SecureBoot that way, because of the missing vars partition.

I've opened https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fkata-containers%2Fkata-containers%2Fissues%2F1231&amp;data=04%7C01%7Csandeep.gupta%40amd.com%7C3d884bd4e4904f858e6308d8b2e83de9%7C3dd8961fe4884e608e11a82d994e183d%7C0%7C0%7C637456057849018749%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&amp;sdata=tUAcbzpVNvm8iiSX1UuOcLAjwcLTNBNQY1MUEAu2%2Bf0%3D&amp;reserved=0. I will add a comment highlighting the difference.


1) You did that run without having the "firmware = " option. If that 
was the case, please send the command-line with the firmware option

(Hypothesis: maybe you are looking at the wrong configuration file, 
e.g. you have a local /etc/ override; that might explain why it 
"worked" with 1.x, although it would then require investigation to 
understand why SEV was enabled without your firmware)

2) Something else removes the firmware setting or causes qemu to not 
receive the -bios option

When "firmware" is specified, qemu should be invoked with the -bios option, and the corresponding commit dates back to early 2018, so I don't expect any difference between 1.x and 2.0 there.


Cheers,
Christophe

Any suggestions please.

I did a quick look. The runtime apparently uses the -bios option when the firmware option is passed, not the -drive option as I thought it would. I'm not entirely sure you can boot OVMF that way. I don't have any idea at the moment why it worked with version 1.x. If you could share with me the 1.x qemu command line option with the firmware option, I'm curious to see what it is.
