I want to use crash on RHEL 7.0. Since crash needs vmlinux file, but I can't find it on /boot folder, only vmlinuxz:

......
vmlinuz-0-rescue-7c50639231494746b5dffc0a1ff84727
vmlinuz-3.10.0-123.el7.x86_64
vmlinuz-3.10.0-123.el7.x86_64.debug
......

I have installed all kernel*.pkg from RHEL 7.0 ISO file:

[root@localhost boot]# yum install kernel*
Loaded plugins: product-id, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
RHEL                                                                                        | 4.1 kB  00:00:00

Package kernel-tools-3.10.0-123.el7.x86_64 already installed and latest version
Nothing to do

So how can I get RHEL 7.0 vmlinux file?

You need to enable 'debuginfo' repository for RHEL and install kernel-debuginfo rpm to get required vmlinux

# rpm -qf /usr/lib/debug/lib/modules/3.10.0-229.14.1.el7.x86_64/vmlinux 
kernel-debuginfo-3.10.0-229.14.1.el7.x86_64
