Dynamips hypervisor process has stopped, return code: -11

[ilezcano]

Running 0.2.17, dynamips keeps crashing with the code in the subject line. I'm able to connect to the console, observe the decompression of the image, and I see messages demonstrating that the configuration is read.

Besides the above, I also see the following part of the error message: C3600 'Ghost': generic_nvram_extract_config: Unknown error -61605

@ilezcano are you on Linux?

Probably same error reported by https://github.com/GNS3/gns3-server/issues/1177

[ilezcano]

Yes, I'm on Linux.

The issue you reference is very similar to mine, though that one seems to focus on the IDLEPC value, and I've not played with mine yet.

This one is probably more related to issue #68.

I have experienced crashes with a similar error messages with some c3640 images while saving the router configuration ("write" command in cli), but I never looked into it more closely.

We are getting the issue on Ubuntu 18.04 too: https://github.com/GNS3/dynamips/issues/90

Please see https://github.com/GNS3/gns3-server/issues/1363#issuecomment-403817051 for a possible workaround on Ubuntu 18.04

I also facin the same problem when i am starting a router with iou it is showing the error.And when i am starting it from ios it gives the following error . Dynamips hypervisor process has stopped, return code: -11 C3600 'Ghost': generic_nvram_extract_config: Unknown error -61605

It is Ubuntu 18 and

when starting the router of IOU it gives the following error

I have the same problem, any soluion ? im on ubuntu20.10

[Jujubabien]

Had the Same issue on pop!_os 20.10 (ubuntu 20.10) : after trying unsuccessfully many workarounds, here's what worked for me.

Since the dynamips i386 package isn't proposed in the ubuntu repos anymore, I installed one from debian (testing / bullseye) : https://debian.pkgs.org/11/debian-nonfree-i386/dynamips_0.2.14-1_i386.deb.html

install it : $ sudo dpkg -i dynamips_0.2.14-1_i386.deb since it has broken dependencies do : $ sudo apt install --fix-broken

And that's it...restarted GNS3 and my dynamips VM now starts fine...

It's not very "clean" but worked for me so I post in case it could help someone...

I don't have time to dig strftime/gmtime_r relationships, but the commenting strftime in common/utils.c helps to get workable dynamips (+GNS3)

void m_flog(FILE *fd,char *module,char *fmt,va_list ap) { struct timespec spec; struct tm tmn; char buf[256];

if (fd != NULL) { clock_gettime(CLOCK_REALTIME, &spec); gmtime_r(&spec.tv_sec, &tmn);

  /*strftime(buf,sizeof(buf),"%b %d %H:%M:%S",&tmn);*/

  fprintf(fd,"%s.%03ld %s: ",buf,(long)spec.tv_nsec/1000000,module);
  vfprintf(fd,fmt,ap);
  fflush(fd);

} }

strftime is crashy... it has crashed on me because the console didn't have a locale set and I've also read other random causes for crashes.

@grossmj Is the timestamp format mandatory? If not then a change to ISO8601 is in order.

I remember we had some crash with strftime / localtime in the past when a timezone was not set. It was fixed in https://github.com/GNS3/dynamips/issues/91

I don't think it is mandatory.
