[VM,6.8] Can not install OpenBSD into vm

CiotBSD · #1 **(View Single Post)** 2nd February 2021

Hi,

Today, I attempt to create a VM OpenBSD on OpenBSD Host.

My computer, normally, can virtualize:

Code:

$ dmesg | egrep '(VMX/EPT|SVM/RVI)'
vmm0 at mainbus0: VMX/EPT (using slow L1TF mitigation)
vmm0 at mainbus0: VMX/EPT (using slow L1TF mitigation)
vmm0 at mainbus0: VMX/EPT (using slow L1TF mitigation)
vmm0 at mainbus0: VMX/EPT (using slow L1TF mitigation)
vmm0 at mainbus0: VMX/EPT (using slow L1TF mitigation)

My vm.conf used:

Code:

$ cat /etc/vm.conf                                                                                                                                                                           

switch "sw" {
	interface bridge0
}

vm "web" {
	disk /home/zou/VM/web.qcow2 format qcow2
	interface { switch "sw" }
	memory 1024M
	owner zou	
}

the iface bridge0 is up:

Code:

$ ifconfig bridge0
bridge0: flags=41<UP,RUNNING>
	description: switch1-sw
	index 4 llprio 3
	groups: bridge
	priority 32768 hellotime 2 fwddelay 15 maxage 20 holdcnt 6 proto rstp
	designated: id 00:00:00:00:00:00 priority 0
	em0 flags=3<LEARNING,DISCOVER>
		port 1 ifpriority 0 ifcost 0
	Addresses (max cache: 100, timeout: 240):
		28:d1:27:d6:f9:31 em0 1 flags=0<>

I created, without problem, the file qcow2, but when I attempt to start to install OpenBSD, it fails!

I tried with the install68.i{mg,so} or directly with bsd.rd, as:
1/

Code:

 # vmctl start -c -m 1G -L -i 1 -r install68.img -d web.qcow2 web

2/

Code:

# vmctl start -m 1G -L -i 1 -r install68.iso -d web.qcow2 web

3/

Code:

doas vmctl start -c -m 1G -L -i 1 -b /bsd.rd -d /home/zou/VM/web.qcow2 web

And yes, I checked with signify both iso and img file. There are OK!

Code:

$ sha256 -C SHA256 install68.i*                                                                                                                                                              
(SHA256) install68.img: OK
(SHA256) install68.iso: OK
$ signify -Cp /etc/signify/openbsd-68-base.pub -x SHA256.sig install68.i*                                                                                                                    
Signature Verified
install68.img: OK
install68.iso: OK

All failed just after the launch.

1/ first method, with iso

Code:

Connected to /dev/ttyp2 (speed 115200)
Boot failed: not a bootable disk
Boot failed: Could not read from CDROM (code 0005)
Boot failed: could not read the boot disk
No bootable device.  Retrying in 60 seconds.

2/ second with img, see:
- https://bin.disroot.org/?c87d8115c47...YMX1BNfZfXquSY

3/ third, with bsd.rd, see:
- https://bin.disroot.org/?3d62113d2fa...eTC8adWq6uwWGE

---

I noticied on log messages, thoses errors:
- https://bin.disroot.org/?1723c27413d...49DHfAuVcTrKhX

And, on dmesg:

Code:

vmx_fault_page: uvm_fault returns 14, GPA=0xffffca78, rip=0xfbd49

---

Result: I cant install VM!

One suggestion? idea?

How did you create /home/zou/VM/web.qcow2?

This works for me:

Code:

vmctl create -s 10G disk.qcow2
doas rcctl -f start vmd
doas vmctl start -m 1G -L -i 1 -r install68.iso -d disk.qcow2 -c test

I didn't create vm.conf or a bridged interface but note that your example configuration file specifies a bridged interface but the vmctl command creates a local network interface for the VM (see the man page for details on the "-L" option).

CiotBSD · #3 **(View Single Post)** 2nd February 2021

I created exactly as wroted into the FAQ virtualisation.

Telling me, "it works for me": It doesn't help!

Solene@, team OpenBSD member, logged on to my station, checked several things, tested the creation. I do have a problem, when starting the VM that kills immediately. We don't understand the why, or the reason!

So you ran the same vmctl create command as I posted above then?

I was just attempting to demonstrate a method that works. Does my posted method work for you? Be sure to remove your bridged interface and vm.conf before trying it.

If my method works for you then it is likely that your bridged interface configuration and/or vm.conf is the cause of your error.

You could also try using the vmctl start command without the -L option but with your bridged interface and vm.conf intact. That option appears to contradict vm.conf and so may be causing the problem.

I should have mentioned that I'm using -current (sorry). You should probably also state explicitly whether you're using -stable or -release.

CiotBSD · #5 **(View Single Post)** 2nd February 2021

OK, I understand your opinion; but:

Code:

# rm -fP /etc/vm.conf
# rm -fP /etc/hostname.bridge0 
# rcctl disable vmd
# rcctl stop vmd    
vmd(ok)
# reboot

After login by SSH:

Code:

$ vmctl create -s 10G disk.qcow2
vmctl: qcow2 imagefile created
$ doas rcctl -f start vmd
vmd(ok)

$ doas vmctl start -m 1G -L -i 1 -r install68.iso -d disk.qcow2 -c test

the problem is elsewhere!

Head_on_a_Stick · #6 **(View Single Post)** 2nd February 2021

Apart from the fact that I'm testing this in -current the only other difference is this:

Code:

~$ dmesg | egrep '(VMX/EPT|SVM/RVI)'
vmm0 at mainbus0: SVM/RVI
~$

^ I'm using an AMD machine so the L1TF mitigation isn't needed.

Unfortunately I don't know how you would go about disabling that mitigation in OpenBSD, perhaps Solene@ can help you with that.

jggimi · #7 **(View Single Post)** 3rd February 2021

I am going to guess that the problem is the "slow L1TF mitigation" needed by your hardware. My Intel processor (i5-2520M) does not produce that message.

Code:

$ dmesg | grep vmm0
vmm0 at mainbus0: VMX/EPT

More info on L1TF: https://en.wikipedia.org/wiki/Foreshadow

@jggimi: I remember about that! It seems possible…
