Re: yum and curl showing illegal instruction

Looks like a hard issue to fix. If it isn't a XEN issue, Redhat might want to convince us to move to KVM ;-) I found it interesting that Steadyfast provides a repo to fix that issue based on a fix from 2013??? https://bugzilla.mozilla.org/show_bug.cgi?id=940794 If you interested in the repo itself r...

Yes. This issue seems to be not that important to them.

I found a post from 17th of May, where someone already posted a workaround to this issue.
Not many CentOS under virtualization. Or not many hosts with AES cpu flags.

Re: yum and curl showing illegal instruction

You could use temporary fix of this problem, by setting the environment variable: "NSS_DISABLE_HW_GCM=1" Thanks for for joining the thread. I had sucess with NSS_DISABLE_HW_AES=1 . I wonder if there is a way, to set NSS_DISABLE_HW_AES=1 global and not for the session. Other solution was to downgrad...

Re: yum and curl showing illegal instruction

I think the actual problem is that the cpuinfo says it has AES but when the system tries to use it, it discovers the support is not there - hence the illegal instruction crash. So you mean that the error is with Xen or a misconfiguration of Xen exposing the wrong CPU flags? The discussions in the b...

Re: yum and curl showing illegal instruction

Looks like this bug in the tracker matches: https://bugs.centos.org/view.php?id=10930&nbn=5 Your idea with the AES flag was my motivation. I checked the different hosts. The issue occure when CPU flag AES is available. On hosts without AES flag no issues occur. Thanks. Wonder if this is a issue on H...

Re: yum and curl showing illegal instruction

Are you on a virtual machine? What is the output form grep -i aes /proc/cpuinfo ? Yes, XenPV. But I have now found some machines which are on the same kernels and didn't show the issue. The logfiles show no yum install errors on the machines with the issue when updating to CentOS 6.8. The update it...

yum and curl showing illegal instruction

Since the last update yum is no longer working correctly. Yum itself doesn't seem to be broken. But I currently cannot pinpoint the cause for crashing. yum update Loaded plugins: fastestmirror Setting up Update Process Loading mirror speeds from cached hostfile Illegal instruction yum --version 3.2....
